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 240 N applied to its edge causes the wheel to have an angular acceleration of 0.862 rad/s. 

(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 4.60 s have elapsed, assuming the force is acting during that time? rad/s
