Chapter 5, Problem 5.88(choose chapter or problem)
In 1887 in Bridgeport, Connecticut, C. J. Belknap built the water slide shown in Figure P5.88. A rider on a small sled, of total mass 80.0 kg, pushed off to start at the top of the slide (point ) with a speed of 2.50 m/s. The chute was 9.76 m high at the top, 54.3 m long, and 0.51 m wide. Along its length, 725 wheels made friction negligible. Upon leaving the chute horizontally at its bottom end (point ), the rider skimmed across the water of Long Island Sound for as much as 50 m, skipping along like a at pebble, before at last coming to rest and swimming ashore, pulling his sled after him. (a) Find the speed of the sled and rider at point . (b) Model the force of water friction as a constant retarding force acting on a particle. Find the work done by water friction in stopping the sled and rider. (c) Find the magnitude of the force thewater exerts on the sled. (d) Find the magnitude of the force the chute exerts on the sled at point .
