A child of mass 15 kg climbs to the top of a slide that is 1.7 m above a horizontal run that extends for 0.50 m at the base of the slide. After sliding down, the child comes to rest just before reaching the very end of the horizontal portion of the slide. (a) How much inter-nal energy was generated during this process? (b) Where did the generated energy go? (To the slide, to the child, to the air, or to all three?)
