Answer to Question #64228 in Mechanics | Relativity for Youssef

Question

The uniform beam AB has a mass of 4.5 kg and is connected between a sliding collar at A and a homogeneous disc of mass 6.8 kg. When the system is released from rest in the position shown, the collar sliders down the vertical guide and the disc rolls without sliding on the horizontal surface. Determine (a) the velocity of the collar when it is about to collide with the spring, and (b) the maximum deflection of the spring after collision.
