Asked by hayley
A string is wrapped around a pulley of radius .20m and momentum of inertia .40 kg•m^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.

force*radius=torque=momentinertia*angularacceleration
angular acceleration=force*radius/momentI
angular acceleration=force*radius/momentI
