Ok! I never even thought of the possibility that it wasn't vertical. So now my thinking is to use torque = 17 N * .025 m and divide that by the moment of inertia MR^2 to get angular acceleration. Then I can just use simple kinematics. Does that sound correct?
Hi, I just don't really understand rotational motion very well, and I don't know how to proceed with this problem.

Thank you both very much. That is exactly what I needed! My only question would be how did you know what the moment of inertia would be for that system?
I am completely stuck on this problem, and was wondering if anyone could point me in the right direction.
