If you lift the front wheel of a poorly maintained bicycle off the ground and then start
Question:
If you lift the front wheel of a poorly maintained bicycle off the ground and then start it spinning at 0.72 rev/s, friction in the bearings causes the wheel to stop in just 12 s. If the moment of inertia of the wheel about its axle is 0.30 kg • m2, what is the magnitude of the frictional torque?
