Afrightened 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 116 n up the slide, the child's kinetic energy increases by 30 j as she moves down the slide a distance of 1.9 m.
(a) how much work is done on the child by the gravitational force during the 1.9 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 1.9 m?
