The combination of an applied force and a friction force produces a constant total torque of35.3N · m on a wheel rotating about a fixed axis. The applied force acts for6.10s. During this time, the angular speed of the wheel increases from 0 to10.3rad/s. The applied force is then removed, and the wheel comes to rest in59.5s.
(a) Find the moment of inertia of the wheel.
(b) Find the magnitude of the torque due to friction.
(c) Find the total number of revolutions of the wheel during the entire interval of65.6s.
