Homework Help: Physics

Posted by hayley on Sunday, July 8, 2012 at 7:12pm.

A string is wrapped around a pulley of radius .20m and momentum of inertia .40 kgm^2. The string is pulled with a force of 28 N. what is the magnitude of the resulting angular acceleration?

Can someone please go through the steps or at least guide me through them. I missed a few days in class and am trying to figure this out without any notes on it or anything.
