Answer:
Their kinetic energies would be the same
Explanation:
This is because, since the force, F acting on them moves the same distance, d, the work done by the force is W = Fd.
Now, from work-kinetic energy principles,
W = ΔK where ΔK = change in kinetic energy of the carts.
Since the work-done is the same for both carts, their change in kinetic energies would also be the same.
Since they start from rest, ΔK = K' - K = K' - 0 = K'
So, the kinetic energies of the carts would be the same
Answer:
I believe the answer is B.
At it's maximum height the acceleration is still 9.8m/s. On the earths surface, all objects are constantly under acceleration due to gravity. It is perculiar, but true. Under acceleration, only the velocity changes (as a general rule).
Answer:
i belive it is A Elliptical

Formula to find the volume of cylinder is pi×r^2×h ; r --radius ; h -- height
Therefore,vol of cylinder is pi×1.5^2×5.3 = 11.925pi = 37.5 ( rounded off to 3s.f)
