15.7-N force is applied to a cord wrapped around a pulley of mass M = 3.63-kg and radius R = 22.5-cm The pulley accelerates uniformly from rest to an angular speed of 25.8 rad/s in 4.92-s. If there is a frictional torque = 1.31-mN at the axle, (a) determine the moment of inertia of the pulley, (b) determine the rough estimate of the moment of inertia. (The pulley rotates about its center)
