H= 0.0055m, R= 3m, How far did the object fall?

Answers

Answer 1

The formula s = (1/2)gt2 = 0.5 * 9.80665 * 82 = 313.8 m can be used to calculate the free fall distance. If you are aware of how high the object is.

How far can you fall into?Most falls occur from a height of 20 to 25 feet (6 to 8 metres), but anything higher than that can be fatal very quickly. According to a 2005 study conducted in Paris on 287 fall victims, falls from 8 storeys (30 metres) or above are always lethal.The highest survival thresholds for a person to tolerate impact velocity in water are ostensibly near to 100 ft/sec (68.2 mph) corrected velocity, or the equivalent of a 186-foot freefall.Nearly half of all fatal falls occur at a height between 0 and 20 feet, according to a study of construction accidents in India. Between 21 and 40-foot deadly falls made up the next-largest group. Alternatively stated, 20 feet is sufficient to be fata.

an object is dropped off a building. if it takes 10 seconds to get halfway to the ground, how long does it take to fall the entire distance? ignore air resistance

Answers

Since the object is dropped off a building, we can assume that it is falling under the influence of gravity. The acceleration due to gravity is 9.8 m/s² and the time it takes to fall halfway to the ground is 10 seconds.

The time it takes for an object to fall a certain distance under the influence of gravity is given by the equation:

t = √(2d/g)

Where t is the time, d is the distance, and g is the acceleration due to gravity.

We know that it takes 10 seconds to fall halfway to the ground, so we can use that information to find the total time it takes to fall the entire distance.

Halfway is half the distance, so we can multiply the time to fall halfway by 2 to find the time to fall the entire distance:

t = √(2d/g) x 2

t = 2 x √(2d/g)

t = √(4d/g)

t = √(4 x d/g)

t = √(d/g)

t = √(d/(9.8 m/s²))

So, we need to know the distance that the object is falling to find the total time it takes to fall the entire distance.

Alternatively, if we know the height of the building, we can use it to find the distance that the object is falling. And then we can use that distance in the above equation to find the total time it takes to fall the entire distance.

Answers

The tension in the string is the same over the entire length of the string, and equals the difference between the weight of the mass, and the acceleration of the cart.

What is meant by acceleration ?

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily.An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.In physics, acceleration is the rate at which the velocity of an object changes in relation to time. According to Newton's Second Law, the sum of all forces acting on an item results in its acceleration. Meter per second squared (m s2) is the unit of acceleration used in the SI system.The definition of acceleration is the rate of change of velocity. Or Acceleration is the term used to describe a change in velocity over time. Acceleration is a vector quantity because velocity is one as well.
