5. A large grinding wheel in the shape of a solid cylinder of radius r = 0.330 m is free to rotate on a frictionless, vertical axis. A constant tangential force of Ft = 250 N applied to its edge causes the wheel to have an angular acceleration of 1.20 rad/s². What are (a) the magnitude of torque acting on the wheel and (b) the moment of inertia of the wheel? %3D net (b) I = %3D
