A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 280 N applied to its edge causes the wheel to have an angular acceleration of 0.906 rad/s2. (a) What is the moment of inertia of the wheel? kg . m (b) What is the mass of the wheel? kg (c) If the wheel starts from rest, what is its angular velocity after 4.40 s have elapsed, assuming the force is acting during that time? rad/s
