Adam and Bobby are twins who have the same weight. Adam drops to the ground from a tree at the same time that Bobby begins his descent down a frictionless slide. If they both start at the same height above the ground, compare their kinetic energies when they hit the ground. In making your comparison, choose from one of the following three options, and explain your choice: 1) They both have same kinetic energy when they hit the ground 2) Adam has a greater kinetic energy than Bobby when they hit the ground 3) Bobby has a greater kinetic energy than Adam when they hit the ground. Part d: Adam and Bobby are twins who have the same weight. Adam drops to the ground from a tree at
