1. The problem statement, all variables and given/known data Yhou built a water slide . A rider on a small sled, of total mass 80.0 kg, pushed off to start at the top of the slide (point A) with a speed of 3.0 m/s. The chute was 10 m high at the top, 55 m long, and 0.50 m wide. Along its length, 725 wheels made friction negligible. Upon leaving the chute horizontally at its bottom end (point B), the rider skimmed across the water of Long Island Sound for as much as 50 m, “skipping along like a flat pebble,” before at last coming to rest and swimming ashore, pulling his sled after him. (c) Find the magnitude of the force the water exerts on the sled. (d) Find the magnitude of the force the chute exerts on the sled at point C just before leaving the slide. 2. Relevant equations PE = mgh KE = 1/2mv2 3. The attempt at a solution PE = KE mgh = 1/2mv2 Stuck! I don't know were to go from here.
