Physics

A torque of 36.2 N · m is applied to an initially motionlesswheel which rotates around a fixed axis. This torque is the resultof a directed force combined with a friction force. As a result ofthe applied torque the angular speed of the wheel increases from 0to 9.5 rad/s. After 6.10 s the directed force is removed, and thewheel comes to rest 60.2 s later.

A- What is the wheel's moment of inertia

B- What is the magnitude of the torque caused by friction

C- From the time the directed force is initially applied, howmany revolutions does the wheel go through?
