asportscar, electro-fiasco i, can accelerate uniformly to 100 km/h in 3.5 s. its maximum braking rate can not exceed 0.7g. what is the minimum time required to go 1.0 km, assuming it begins and ends at rest?

Answers

The minimum time required to travel 1.0 km is 8.75 seconds.

What is travel?

Travel is the movement of people from one place to another, usually over a certain distance and for a certain period of time. It can be done for many reasons, including pleasure, business, or to visit family or friends.

This can be calculated by taking the total distance traveled (1.0 km) and dividing it by the average speed (100 km/h). The average speed is 100 km/h because the car accelerates uniformly from 0 km/h to 100 km/h in 3.5 seconds.
Therefore, the total time required is 10 seconds (1 km / 100 km/h). However, this does not take into account the deceleration time of the car, which must also be taken into account.
The maximum braking rate of the car is 0.7 g, which is equivalent to 7 m/s2. Since the car must come to a complete stop at the end of the 1.0 km journey, the time required for deceleration must be calculated. This can be done using the equation:
Time for deceleration = (Final Velocity - Initial Velocity) / Acceleration
Since the initial velocity is 0 m/s and the final velocity is 0 m/s, the equation simplifies to:
Time for deceleration = 0 / 7 m/s2 = 0 seconds
Therefore, the total time required to travel 1.0 km is 10 seconds (for acceleration) + 0 seconds (for deceleration) = 10 seconds. Subtracting this from the total time required gives us the minimum time required to travel 1.0 km, which is 8.75 seconds.

The body and through a specific angle experience angular accelerations of 0.87266 rad/sec2 and 12566.8 rad, respectively.

Calculate angular acceleration ?

A rotating rigid body's angular velocity rises from 500 to 1500 rev/min under the given conditions.

Time= 120s

Finding - Angle and angular acceleration

The basic idea is that we must change rev/min to rad/sec.

ωf= ωi + αt

ωf- ωi = αt

Formula for angular acceleration: = [f- i]/t

Angle deviation formula: =it + t2/2

Calculations-

Rev/Min to rad/Sec conversion

I equals 500 rev/min

500 x 2 rad/rev x 1 minute and 60 seconds equals 52.3598 rad/sec.

f = 1500 rev/min

=1500 x 2 rad/rev x 1 minute and 60 seconds = 157.079 rad/sec

52.3598 rad/sec for I

ωf=157.079rad/sec

Now, to calculate angular acceleration, use the formula: [f- i]/t.

52.3598 rad/sec − 157.079 rad/sec = 120

1.872666 rad/sec

To calculate the angle deviated, enter -=i t + t2/2.

a ferry boat shaped just like a brick is 7.7 m wide and 6.2 m long. when a truck pulls onto it, the boat sinks 5.57 cm in the water. what is the weight of the truck? the acceleration of gravity is 9.81 m/s 2 . answer in units of n.

Answers

The weight of the truck is approximately 254,979 N or 254.9 kN

To find the weight of the truck, we can use the principle of buoyancy, which states that the buoyant force exerted on an object submerged in a fluid is equal to the weight of the fluid that is displaced by the object.

First, we need to find the volume of the water displaced by the boat when the truck pulls onto it. We can use the dimensions of the boat and the amount it sinks in the water to calculate this. The boat is shaped like a brick, so we can assume it has the same dimensions on the top and bottom.

The boat's width is 7.7 m and its length is 6.2 m. The boat sinks 5.57 cm or 0.0557 m in the water.

The volume of the water displaced is the product of the boat's width, length, and the amount it sinks in the water.

Volume of water displaced = 7.7 m x 6.2 m x 0.0557 m = 25.9 m^3

Next, we can use the density of water, which is about 1000 kg/m^3 to find the weight of the water displaced.

Weight of water displaced = 1000 kg/m^3 x 25.9 m^3 = 25900 kg

Finally, we can use the weight of the water displaced to find the weight of the truck using the equation of buoyancy force which is equal to the weight of the fluid displaced.

Weight of truck = weight of water displaced x g

Weight of truck = 25900 kg x 9.81 m/s^2 = 254979 N

Therefore, the weight of the truck is approximately 254,979 N or approximately 254.9 kN.

_____ is the magnitude of gravitational force acting on an object.

Question 5 options:

Answers

Answer:

Weight

Explanation:

The magnitude of the gravitational force acting on an object is weight of the object.

Answer: Option B

Explanation:

Any kind of force is a vector quantity having magnitude and direction. And it is also known that all kinds of forces obey Newton’s second law of motion. This means that the magnitude of any kind of force will be equal to the product of mass and acceleration exhibited by the object.

As the term acceleration is also a vector quantity in the second law of motion, so the direction of acceleration will define the direction of force. Thus for the gravitational force, the acceleration will be acting downward and the acceleration of the object pulled due to gravitational force will have acceleration due to gravity.

So the Newton’s second law of motion representation of gravitational force will be

                     

Now this product is also equal to the weight of the object as weight of any object is defined as the mass of the object influenced by gravitational pull.

Answer is weight…it’s the force with which a body is attracted toward the earth or a celestial body by gravitation and which is equal to the product of the mass and the local gravitational acceleration.

An aircraft decelerate at 0.5 m/.after 8 minute it velocity ha dropped to 160 m/ .find it initial velocity.

Answers

Acceleration (a) is the change in velocity (Δv) versus the change in time (Δt), given by the formula a = Δv/Δt. This allows you to measure how quickly the velocity changes in meters per second (m/s^2). Acceleration is also a vector quantity, so it contains both magnitude and direction. Negative acceleration is termed as deceleration

Deceleration can be calculated by dividing the final velocity minus the initial velocity by the time it takes for this velocity to drop.

The known and unknown quantities from the question are as follows:

u = initial velocity = ? m/s

v = final velocity = 160 m/s

a = acceleration = -0.5 m/s²

t = time interval = 8 min × 60 s/1 min = 480 s

Calculate the initial velocity using the following kinematic equation.

v = u + at

u = v - at

u = 160 m/s - (-0.5 m/s² × 480 s) = 400 m/s

Answers

The angular velocity is infinity.

it's not possible to calculate the kinetic energy change when the angular velocity becomes infinity, it's an abstract concept.

What is angular speed?

PART 1

The angular velocity of an object is given by the formula:

ω = v/r

where

v is the linear velocity and

r is the distance from the axis of rotation.

The man's initial angular velocity is:

ω = (0.37 rev/s) * (2π rad/rev)

= 2.34 rad/s

As the man moves closer to the center, his distance from the axis of rotation decreases, so his angular velocity will increase.

To find the new angular velocity, we can use the same formula:

ω = v/r

since the radius decreases to 0, the angular velocity becomes infinity.

PART 2

The change in kinetic energy is given by the formula:

ΔK = 1/2 * I * (ω_f^2 - ω_i^2)

where

I is the moment of inertia and ω_i and ω_f are the initial and final angular velocities respectively.

For a solid cylinder, the moment of inertia is:

I = (1/2) * m * r^2

where

m is the mass and r is the radius.

The moment of inertia for the merry-go-round is:

I = (1/2) * (29 kg) * (1.2 m)^2

= 15.12 kg * m^2

The change in kinetic energy can be calculated as:

ΔK = 1/2 * (15.12 kg * m^2) * (∞^2 - (2.34 rad/s)^2)

Answers

The number of revolutions per minute (rpm) by dividing the speed by the circumference of the path is 14.89 rpm.

What is revolutions?

A revolution is a radical, pervasive and often violent change in a society's political, economic, and social structures. It is typically associated with a dramatic shift in power, from one group of people to another, either through the overthrow of a government or through other means such as widespread protest or civil disobedience.

The centripetal acceleration of an object in a circular path is given by the equation:
a_centripetal = (v^2) / r
where v is the speed of the object, and r is the radius of the circular path.
We know the radius of the path is 5.00 m and the centripetal acceleration should be 1.90 times that due to gravity. The acceleration due to gravity is 9.8 m/s^2. Therefore, the centripetal acceleration should be:
a_centripetal = 1.90 * 9.8 = 18.82 m/s^2
Now we can solve for the speed of the riders:
v = sqrt(a_centripetal * r) = sqrt(18.82 * 5.00) = 12.76 m/s
Finally, we can calculate the number of revolutions per minute (rpm) by dividing the speed by the circumference of the path:
rpm = (v / (2 * pi * r)) * 60 = (12.76 / (2 * pi * 5.00)) * 60 = 14.89 rpm.

Answers

The body will be at a temperature of 60°F after around 72 minutes.

The problem can be solved using Newton's law of cooling, which states that the rate of change of temperature of an object is proportional to the difference in temperature between the object and its surroundings. Mathematically, this can be represented as:

T(t) = T_s + (T₀ - T_s) e^(-kt)

where T(t) is the temperature of the object after time t, T₀ is the initial temperature of the object, T_s is the temperature of the surroundings, t is time and k is a constant of proportionality called the cooling coefficient.

Use the initial condition T = 90°F at t = 10 min, T_s = 50°F, T₀ = 100°F to solve for the value of k.

T(t) = T_s + (T₀ - T_s) e^(-kt)

90°F = 50°F + (100°F - 50°F) e^(-k)(10)

40°F = 50°F e^(-k)(10)

e^-10k = 0.8

k = 0.0223

thus we can calculate the time it takes for the body to reach a temperature of 60°F:

T(t) = T_s + (T₀ - T_s) e^(-kt)

60°F = 50°F + (100°F - 50°F) e^(-0.0223)(t)

10°F = 50°F e^(-0.0223)(t)

e^(-0.0223)(t) = 0.2

t = 72.1721

She discovered that radiation could be released when a neutron, a tiny particle, was fired into another atom. Fission is the process by which a heavy, unstable nucleus splits into two lighter nuclei, whereas fusion is the joining of two light nuclei to release large amounts of energy.

In the position time graph, between 4 and 6 seconds, the object is at rest because the change in position with time is zero.

What is position - time graph?

A position - time graph is a type of graph in which the position of an object is plotted against time of motion of the object.

In a position time graph, the slope of the graph is the velocity of the object since velocity is defined as the change in displacement with change in time.

From the given position - time graph, between 4 to 6 seconds, the change in position of the object is constant, hence the velocity of the object will be zero, so we can conclude that the object is at rest between 4 to 6 seconds.

2 attempts left enter your answer in the provided box. a metal ball-bearing with a circumference of 41.3 mm weighs 8.77 g. what is the density of the metal in g/cm3 (v of a sphere

Answers

A metal ball bearing that has a 41.3 mm circumference weights 8.77 g. the metal has a density of 7.816 g/cm3. The mass of a material per unit of volume is its density.

We must first estimate the volume of the metal ball bearing before dividing the mass by the volume to obtain the density of the metal.

First  calculate the radius,

C = 2πr = 41.3mm = 4.13cm

here, we can find the radius,

r = c/2π = 4.13/2π = 0.65cm

to find the volume,

V = 4/3πr³

V = 4/3 π X 0.65³

V =  1.14cm³

now, to calculate density,

m = 8.77g

d = m/v

d = 8.77/1.14

d = 7.6 g/cm³

Finally, by dividing the mass by the volume, we get at the metal's density, which comes to around 7.6 g/cm3.

what is the approximate line-to-ground arcing fault value on a 480/277-volt system where the line-line-line fault current has been calculated to be 30,000 amperes?

Answers

On a 480/277-volt system where the line-line-line fault current has been estimated to be 30,000 amperes, the approximate line-to-ground arcing fault value is 17,321 amperes.

The approximate line-to-ground arcing fault value for a 480/277-volt system is determined by calculating the line-line-line fault current and then dividing it by the square root of three (√3). The value of the line-line-line fault current must first be determined, which is 30,000 amperes in this case.

Next, the line-to-ground arcing fault current value is calculated by dividing the line-line-line fault current by the square root of three (√3), which is equal to 17,321 amperes. To arrive at this number, we use the following formula:

Line-to-ground arcing fault current = line-line-line fault current / √3

Therefore, the approximate line-to-ground arcing fault current value for a 480/277-volt system where the line-line-line fault current has been calculated to be 30,000 amperes is 17,321 amperes.

To summarize, the approximate line-to-ground arcing fault value for a 480/277-volt system is determined by calculating the line-line-line fault current, which is 30,000 amperes in this case, and then dividing it by the square root of three which is equal to 17,321 amperes. This is the approximate line-to-ground arcing fault current value that would be expected in such a system.

a point charge of 8.74 x 10-6 c is at the origin while a second point charge of -5.91 x 10-6 c is at the coordinates (0.53, 0.41) meters. in degrees relative to the positive x direction, what is the direction of the force exerted on the charge at the origin?

Answers

The direction of the force on the charge at the origin is towards the charge at (0.53, 0.41) m, since the charges have opposite signs and attract each other.

The direction of the force exerted on a point charge at the origin by a second point charge can be found using Coulomb's law, which states that the force between two point charges is proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula for the force is:

F = k * q1 * q2 / r^2

where k is the Coulomb constant (8.99 x 10^9 N * m^2 / C^2), q1 and

q2 are the charges, and

r is the distance between the charges.

To find the direction, we must first find the components of the force along the x and y axes.

Then, we can use arctan to find the angle relative to the positive x direction.

The distance between the charges can be found using the Pythagorean theorem:

[tex]r = \sqrt{((0.53 m)^2 + (0.41 m)^2)[/tex] = 0.65 m

The x and y components of the force can then be found using the formula:

Fx = F * cos(θ) = k * q1 * q2 * x / r^3

Fy = F * sin(θ) = k * q1 * q2 * y / r^3

where θ is the angle between the force and the positive x direction, and x and y are the x and y components of the displacement vector between the charges, respectively.

Finally, the direction of the force can be found using arctan:

θ = arctan(Fy / Fx)

The direction of the force on the charge at the origin is towards the charge at (0.53, 0.41) m,

at a specific moment, a falling object with mass 4 kg is moving 7 m/s and is 3 meters above the ground. how many joules of mechanical energy does the object have?

Answers

A falling item with a mass of 4 kg is 3 metres above the earth and is travelling at a speed of 7 m/s at that precise time. The item has a mechanical energy of 216.4 Joules.

A falling object's kinetic energy (KE) and potential energy may be used to compute its mechanical energy (PE).

KE = 1/2 mv ²

= 1/2 X 4 X 14 = 98

where m is the item's mass and v is its velocity,

The equation PE = m * g * h gives the potential energy of an item.

PE =  4 X 9.8X 3 =  117.6

E = KE + PE gives the object's total mechanical energy.

E = 98 + 117.6

= 215.6 J

a person walks first at a constant speed of 5.10 m/s along a straight line from point circled a to point circled b and then back along the line from circled b to circled a at a constant speed of 3.30 m/s. (a) what is her average speed over the entire trip?

Answers

The average speed of that person with two constant speed for a certain distance is 4 m/s.

How to calculate average speed over the entire trip?

Assume the distance from point a and b is c, As per data given velocity from a to b = 5.10 m/sec. So,

time a to b = c : 5.10.

Since the constant speed is 3.3. then

time b to a = c : 3.30

The we can determine the average speed as follow:

Total distance = c + c = 2c

Total time = time a to b + time b to a

Total time = c : 5.10 + c : 3.30

Total time = 0.196c + 0.303c

Total time = 0.499c

Average speed = total distance : total time

Average speed =  2c : 0.499c

Average speed = 4.00801603206

Let round the result, so the average speed = 4 m/s
