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