The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.
Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,
Using Formula:
K.E=[tex]1/2mv^{2}[/tex]
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=[tex]1/2(0.125)(4)^{2}[/tex]
K.E=[tex]1/2(0.125)(16)[/tex]
K.E=1/2(2)
K.E=1
When the mass of the bottle is 0.250 kg, the Kinetic Energy is
K.E=[tex]1/2(0.250)(4)^{2}[/tex]
K.E=1/2(0.125)(16)
K.E=1/2(4)
K.E=2
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=[tex]1/2(0.375)(4)^{2}[/tex]
K.E=1/2(0.375)(16)
K.E=1/2(6)
K.E=3
When the mass of the bottle is 0.500 kg, the Kinetic Energy is
K.E=[tex]1/2(0.500)(4)^{2}[/tex]
K.E=1/2(0.500)(16)
K.E=1/2(8)
K.E=4
Now we can calculate the change in kinetic energy (ΔKE):
ΔKE = KE(final) - KE(initial)
= 4 kg m*2/s*2 - 1 kg m*2/s*2
= 3 kg m*2/s*2

Why is it important to track our carbon and ecological footprint?
Answer: I got you Fam
Explanation:
it is one competing demand for biologically productive space
Answer:
The carbon footprint is a very important means to understand the impact of a person's behavior on global warming. This is why someone who effectively wants to contribute to stopping global warming, at least on an individual scale, needs to measure and keep track of their personal carbon footprint.
Why is it important to track your ecological footprint?
The Ecological Footprint is a simple metric. It is also uniquely comprehensive. Not only does it measure humanity's demand on our planet's ecosystems, but it is also key to understanding the inter-related pressures of climate change on the natural ecosystems on which humanity depends.
Why is knowing your carbon ecological footprint important?
Knowing your personal or organisational carbon footprint is useful for the following reasons: it enables you to identify and reduce GG emissions, it allows corporations to publish their environmental performance statistics, it can be used as information to raise awareness of environmental costs.
Hope this helps :)
