Q1 A tow rope pulls a skier up the slope at constant speed. What energy transfer (or transfers) is taking place? Take the system to be skier + Earth + slope + Earth A. W -> Ug B. W -> K C. W -> Eth D. Both A and B. E. Both A and C Q2 Below is a graph of potential energy versus position for a particle moving along the x axis. The total mechanical energy of the system is indicated by the dashed line. At t =0 the particle is somewhere between points A and G. For later times, answer the following questions. U(x) 1. Where is K max? 2. Where is v zero? 3. Where is F zero? 4. Where is |F| max? 5. Where are (un)stable equilibria
