A flywheel with initial angular velocity w0 undergoes deceleration due to fric- tional forces, with the torque on the axle being proportional to the square root of its angular velocity. Calculate the mean angular velocity of the wheel averaged over the total deceleration time.

Solution:
A flywheel with initial angular velocity w0 undergoes deceleration due to fric-
