1. The problem statement, all variables and given/known data 2. Relevant equations Kinetic Energy = 0.5 I w^2 v = r * w torque = Inertia * angular acceleration 3. The attempt at a solution That's the problem. I have no idea where to start. I assume that the end goal is to find the angular velocity, and convert to linear velocity, but I don't know how to go about doing that. Any hints are appreciated.
