Halliday, Resnick & Walker — Kinetic Energy and Work: Problem 60
A frightened child is restrained by her mother as the child slides down a frictionless playground slide. If the force on the child from the mother is 100 N up the slide, the child’s kinetic energy increases by 30 J as she moves down the slide a distance of 1.8 m. (a) How much work is done on the child by the gravitational force during the 1.8 m descent? (b) If the child is not restrained by her mother, how much will the child’s kinetic energy increase as she comes down the slide that same distance of 1.8 m?
