You start spinning the front wheel of a bicycle at 0.62 rev/s. in 15 sec, the wheel stops to spin because of the friction in the bearings. if the moment of inertia of the wheel about its axle is 0.25 kh x m2, what is the magnitude of the frictional torque?

If you lift the front wheel of a poorly maintained bicycle off the ground and then start it spinning at 0.66 rev/s, friction in the bearings causes the wheel to stop in just 13 s. If the moment of inertia of the wheel about its axle is 0.33 kg⋅m2, what is the magnitude of the frictional torque?

How to solve?
experimental bicycle wheel is placed on a test stand so that it is free to turn on its axle. If a constant net torque of is applied to the tire for 2.00 s, the angular speed of the tire increases from 0 to 100 rev/min. The wheel is brought to rest by friction in its bearings in 125 s. Assume the 2. A 5.00 N-m external torque is then removed, and the the wheel is rotating is...
