Question

A torque of 45 N m producing a counterclockwise rotation is applied to a wheel about its axle.
A frictional torque of 12 N m acts on the axle.
(a) What is the net torque about the axle of the wheel?
(b) If the wheel is observed to accelerate at a rate of 6.2 rad/s² under the influence of thesetorques, what is the rotational inertia of the wheel?
