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 210 N applied to its edge causes the wheel to have an angular acceleration of 1.161 rad/s2.

(b) What is the mass of the wheel?

torque= momentInertia*angacceleration

210*.330= moment Inertia*1.161

look up the momentu of inertia here:http://www.physics.uoguelph.ca/tutorials/torque/Q.torque.inertia.html
and solve for mass
