2. The 12-kg rod AB is pin connected at A and subjected to a couple moment of M = 15 N-m. If therod is released from rest when the spring is unstretched at 0 = 30°, determine the rod's angularvelocity at the instant 0 = 60°. As the rod rotates, the spring always remains horizontal,because of the roller support at C.k = 40 N/mB0.75 mM = 15 N- m,
