Atorque of 35.6 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 10.1 rad/s. after 5.90 s the directed force is removed, and the wheel comes to rest 59.0 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
