A child moves down a long slide, as shown in Fig. 4.1. Y X surface of slide child Fig. 4.1 (not to scale) The child moves from rest at the top end X of the slide. An average resistive force of 76 N opposes the motion of the child as they move to the lower end Y of the slide. The kinetic energy of the child at Y is 300 J. The decrease in gravitational potential energy of the child as it moves from X to Y is 3200 J.
