A torque of 60 N·m producing a counterclockwise rotation is applied to a wheel about its axle. A frictional torque of 10 N·m acts at the axle.
a. What is the net torque about the axle of the wheel?
b. If the wheel is observed to accelerate at the rate of 2 rad/s² under the influence of these torques, what is the rotational inertia of the wheel?
