2. The 12-kg rod AB is pin connected at A and subjected to a couple moment of M = 15 N-m. If the rod is released from rest when the spring is unstretched at e = 30°, determine the rod's angular velocity at the instant 0 = 60°. As the rod rotates, the spring always remains horizontal, because of the roller support at C. k = 40 N/m 0.75 m M= 15 N m
