1. The problem statement, all variables and given/known data Explain why the kinetic energy of the skier at the bottom of the hill is not equal to the gravitational potential energy of the skier at the top of the hill. 2. Relevant equations n/a 3. The attempt at a solution I think the answer is because the bottom of the hill is not at surface level, and therefore there is still gravitational potential energy. I just wanted to double check and make sure I'm not missing anything. Thanks!
