1. The problem statement, all variables and given/known data I included the problem as an attachment. There is not question other than the problem. It was on a white board. 2. Relevant equations I have no idea what to do with the downwards vector. I vaguely remember that I can't do anything, but I'm not sure. 3. The attempt at a solution In the second attachment. Thank you everyone for your help. I really want to understand this. PS. My notation is a total disaster. What is the Y and what is the X?
