Help with Ap physics? 1. Mr. x and his dad are about to ski down a mountain. They are on identical skis, but Mr. x's dad has more mass. They both start from rest, air resistance is negligible, but friction between the skis and the mountain is not. The zero gravitational potential energy line is at the bottom of the mountain. Mr. x says "Since you have more mass, The force of friction will do more work on you and you will lose more energy than I will on the way down. That means I will have more kinetic energy than you will at the bottom and I will be going faster. Mr. x's dad says "You're forgetting about the fact that there is also more gravitational potential energy stored between me and the Earth. Therefore I will have more kine
