A 30-lb sphere A is held at the 62 angle shown and released. It strikes the 10-lb sphere B. The coefficient of restitution for this collision is e = 0.64. Sphere B is attached to the end of a light rod that pivots freely about point O. If the spring of constant k = 108 lb/ft is initially unstretched, determine the maximum rotation angle of the light rod after impact. Answer: 0 = 17" 62 24" i B 24"
