Question: A thin circular rod is supported in a vertical plane by a bracket at A. Attached to the bracket and loosely wound around the rod

A thin circular rod is supported in a vertical plane by a bracket at A. Attached to the bracket and loosely wound around the rod is a spring of constant k = 40 N/m and undeformed length equal to the arc of circle AB. A 200-g collar C, not attached to the spring, can slide without friction along the rod. Knowing that the collar is released from rest when θ = 30o, determine

(a) The maximum height above point B reached by the collar,

(b) The maximum velocity of the collar.
