A wheel is disconnected from a motor and come to rest from 14,000 rpm because of a 0.90 m·N frictional torque.

1) If the mass of the wheel is 4.1 kg and we assume the wheel is a solid cylinder of radius 79 mm, what is its moment of inertia?

kg·m2

2) How long will it take to come to rest?

3) How many revolutions has the wheel turned before coming to rest?
