Question: A 0.6-lb collar A is released from rest, slides down a frictionless rod, and strikes a 1.8-lb collar B which is at rest and supported

A 0.6-lb collar A is released from rest, slides down a frictionless rod, and strikes a 1.8-lb collar B which is at rest and supported by a spring of constant 34 lb/ft. Knowing that the velocity of collar A is zero immediately after impact, determine

(a) The coefficient of restitution between the two collars,

(b) The energy lost in the impact,

k = 34 lb/ft B 30 1.8 lb 36 ft 0.6 lb
