The figure to the right shows a pool slide of length 5.50 m. The end point of the slide is at 30.0 cm above the water level on the pool. During a summer vacation, an initially at rest 34.5 kg child slides from the top and splashes into the pool water at a speed of 8.00 m/s. While sliding, the child encounters a constant friction of 45.0 N. (a) What is the speed of the child at the end of the slide? (b) At what height above the water leyel should the pool slide start? h 1 30.0 cm 5.50 m
