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 260 N applied to its edge causes the wheel to have an angular acceleration of 0.795 rad/s2.

(a) What is the moment of inertia of the wheel?

1 kg ยท m2

(b) What is the mass of the wheel?

2 kg

(c) If the wheel starts from rest, what is its angular velocity after 4.70 s have elapsed, assuming the force is acting during that time?

3 rad/s
