Two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. When the balls reach the ground, how do the kinetic energies of the two balls compare?
A. The lighter ball has more kinetic energy than the heavier ball because it had mass.
B. The heavier ball has more kinetic energy than the lighter ball because it has more mass
C. Both balls have the same kinetic energy because they were dropped from the same height.
