7kinetic energy is decreasing in B
The answer to this question is going to be False
Answer: 585 J
Explanation:
We can calculate the work done during segment A by using the work-energy theorem, which states that the work done is equal to the gain in kinetic energy of the object:

where Kf is the final kinetic energy and Ki the initial kinetic energy. The initial kinetic energy is zero (because the initial velocity is 0), while the final kinetic energy is

The mass is m=1.3 kg, while the final velocity is v=30 m/s, so the work done is:

They both release greenhouse gases, I think
Answer:
The person above me is right i had a test a couple of days ago and thats kinda what u put and got it right!
