Multiple concept problem: A bike wheel having a moment of inertia of 0.09 kg-m2 has an initial angular speed of 3 rev/s and gradually comes to rest due to a frictional force. The frictional force is caused by a torque of 1.0 N-m. Assuming the angular deceleration remains constant during the entire period, determine how much time it would require for the wheel to come to a stop.
