1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution Well, I tried working on this problems a few different ways and kept hitting a dead end. The work in "relevant equations" was my last attempt. I have spent well over an hour on this problem and I am ridiculously frustrated. Our professor never covered this type of problem in our course and I just can't seem to figure it out on my own. I found the force of the rope the man is holding onto to be 935N, which I am almost certain is right. However, I am not sure how to go about solving work-energy for the pulley. I don't know how to incorporate torque forces into the work-energy equation. If someone could help point me in the right direction, I would greatly appreciate it.
