1. The problem statement, all variables and given/known data http://imgur.com/koz4PpI 2. Relevant equations 3. The attempt at a solution I was able to calculate the net torque on the pulley as 55.88 and the Inertia as .352. Those could be wrong, but that's as far as I could get. I really have no idea. Any kind of help/explanation would be wonderful!
