Chapter 19.4, Problem 41P
Tests of impact on the fixed crash dummy are conducted using the 300-lb ram that is released from rest at θ = 30º, and allowed to fall and strike the dummy at θ = 90º. If the coefficient of restitution between the dummy and the ram is e = 0.4, determine the angle θ to which the ram will rebound before momentarily coming to rest.

A 23-lb sphere A is held at the 60° angle shown and released. It strikes the 8-lb sphere B. The coefficient of restitution for this collision
is e=0.60. Sphere B is attached to the end of a light rod that pivots freely about point O. If the spring of constant k = 89 lb/ft is initially
unstretched, determine the maximum rotation angle of the light rod after impact.
