An experimental bicycle wheeel isplaced on a test stand so that it is free to turn on itsaxle. If a constand net torque of 5.00Nm is applied to thetire for 2.00s, the angular speed of the tire increases from zeroto 100 rev/min. The external torque is then removed, and thewheel is brought to rest by friction in its bearings in 125s.

Compute:

a) the moment of inertia of the whell about the rotation axis.

b) the friction torque

c) the total number of revolutions made b the wheel in the 125stime interval.
