Wall excerts work on skater: Please help :( 1. The problem statement, all variables and given/known data A 69.0-kg short-track ice skater is racing at a speed of 11.0 m/s when he falls and slides into a padded wall that brings him to rest. Assuming that he does not lose any speed during the fall or while sliding across the ice, how much work is done by the wall while stopping the ice skater? 2. Relevant equations Ke=1/2mV^2 W=1/2m(Vf^2+Vi^20 W=Fdcos() F=ma or F=mg 3. The attempt at a solution I am not sure what I am doing. I attached an image of my work.
