1. The problem statement, all variables and given/known data Please see attached photo. It is problem 54. My difficulty is that I am not sure if I marked out the correct forces in the work-force equation. Without the height, I can't find the angle. I was going to use the formula: Δx=radius (times) Δθ However, I'm not even sure this is the right equation to use once I find the height. Should I use kinematic equations instead? 2. Relevant equations Attached photo listing useful information for solving equation. 3. The attempt at a solution Attached photo, written on notebook paper. Thanks for your help!
