Predict/Explain When a ball of mass m is dropped from. rest from a height h, its kinetic energy just before landing is K. Now, suppose a second ball of mass Am is dropped from rest from a height h/4. (a) Just before ball 2 lands, is its kinetic energy 4K, 2K, K, K/2, or K/4? (b) Choose the best explanation from among the following:
I. The two balls have the same initial energy.
II. The more massive ball will have the greater kinetic energy.
III. The reduced drop height results in a reduced kinetic energy.
