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 internal 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?)
