A child is riding downhill in a wagon with a combined mass of 28 kg. Suppose the wagon’s speed increases from 2.4 m/s to 3.7 m/s, and the kinetic energy therefore increases by 110 J. What is a likely source of this change in kinetic energy? *
A) gravity
B) pushed by a friend or parent
C) gaining kinetic energy from the initial kinetic energy
D) converted from the potential energy of being higher on the hill
