A torque of 35.0 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 6.10 s the directed force is removed, and the wheel comes to rest 60.2 s later. (a)What is the wheel's moment of inertia (in kg ·...
