If the coefficient of restitution between A and B is e , and the coefficient of kinetic friction between the plane and the block is k , determine the distance block B slides before stopping. Given: W A 1lb = k 0.4 = W B 10 lb = v 20 ft s = g 32.2 ft s 2 = e 0.6 = Solution: Guesses v A2 1 ft s = v B2 1 ft s = d 1f t = Given W A g v W A g v A2 W B g v B2 + = ev v B2 v A2 = 1 2 W B g v B2
