The combination of an applied force and a friction force produces a constant total torque of 36.6 N · m on a wheel rotating about a fixed axis. The applied force acts for 6.20 s. During this time, the angular speed of the wheel increases from 0 to 9.8 rad/s. The applied force is then removed, and the wheel comes to rest in 59.7 s. (a) Find the moment of inertia of the wheel. 1 kg · m2 (b) Find the magnitude of the torque due to friction. 2 N · m (c) Find the total number of revolutions of the wheel during the entire interval of 65.9 s.
