A torque of 35.9 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 9.7 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 · m2)?

kg · m2

(b)

What is the magnitude of the torque caused by friction (in N · m)?

N · m

(c)

From the time the directed force is initially applied, how many revolutions does the wheel go through?

revolutions
