A 1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an un-deformed length of 5 in. and a constant k = 10 lb/ft. Knowing that the collar is released from being held at A determine the speed of the collar and the normal force between the collar and the rod as the collar passes through B.
