The pulley shown in Figure has radius R and moment of inertia I. One end of the mass m is connected to a spring of force constant k, and the other end is fastened to a cord wrapped around the pulley. The pulley axle and the incline are frictionless. If the pulley is wound counter clockwise so that the spring is stretched a distance d from its unstretched position and is then released from rest, find (a) the angular speed of the pulley when the spring is again unstretched and (b) a numerical value for the angular speed at this point if I= 1.00 kg.m2, R= 0.300 m, k = 50.0 N/m, m = 0.500 kg, d = 0.200 m, and q = 37.0 degrees
