Problem 29

A0.21-kg apple falls from a tree to the ground, 4.0 m below. Ignoring air resistance, determine the apples kinetic energy, K, the gravitational potential energy of the system, U, and the total mechanical energy of the system, E, when the apples height above the ground is (a)4.0 m, (b)3.0 m, (c)2.0 m, (d)1.0 m, and (e) 0 m. Take ground level to be
