A wheel free to rotate about its axis that is not frictionless isinitially at rest. A constant external torque of +48 N·m is appliedto the wheel for 24 s, giving the wheel an angular velocity of +590rev/min. The external torque is then removed, and the wheel comesto rest 120 s later. (Include the sign in your answers.)
(a) Find the moment of inertia of the wheel. (kg*m^2)
(b) Find the frictional torque, which is assumed to be constant.(N*M)
