The combination of an applied force and a constant frictional forceproduces a constant total torque of 35.8 N·m on a wheel rotatingabout a fixed axis. The applied force acts for 6.06 s. During thistime the angular speed of the wheel increases from 0 to 10.2 rad/s.The applied force is then removed, and the wheel comes to rest in59.1 s.
(a) Find the moment of inertia of the wheel.
(b) Find the magnitude of the frictional torque.
(c) Find the total number of revolutions of the wheel.
