Answer

a. The potential energy of A is greater than B in the initial setup. The potential energy of B is greater than A in the final setup. b. The potential energy of A was converted into kinetic energy when it rolled down the ramp.

Work Step by Step

a. The potential energy of A is greater than B in the initial setup as A being held on a higher slope than B which is rolling. The potential of B is greater than A in the final setup as it at a higher slope than A. b. The potential energy of A was converted into kinetic energy when it rolled down the ramp by the law of conservation of energy which states that energy must be converted.
