Homework Statement


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 270 N applied to its edge causes the wheel to have an angular acceleration of 0.984 rad/s2.

If the wheel starts from rest, what is its angular velocity after 4.30 s have elapsed, assuming the force is acting during that time?

Homework Equations


Moment of intertia is 90.457kg/m2
mass of wheel is 1661.29kg


The Attempt at a Solution



I was able to find moment of inertia and mass of wheel above...not sure about angular velocity. I can't find the right equation what uses I.
