A torque of 36.8 N. m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 10.5 rad/s. After 5.80 s the directed force is removed, and the wheel comes to rest 59.4 s later. (a) What is the wheel's moment of inertia (in kg • m2)? kg - m2 (b) What is the magnitude of the torque caused by friction (in N- m)? N.m (c) From the time the directed force is initially applied, how many revolutions does the wheel go through? revolutions
