1. The problem statement, all variables and given/known data An extreme skier, starting from rest, coasts down a mountain that makes an angle of 25.0° with the horizontal. The coefficient of kinetic friction between her skis/snow is 0.200. She coasts for a distance of 10.4 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.50 m below the edge. How fast is she going just before she lands? 2. Relevant equations W = (F cos theta)*displacement W = KEf - KE0 Kinetic friction = coefficient of kinetic friction * normal force Weight = mg 3. The attempt at a solution I tried combining all of these, but i need the mass to do something. I simply can't figure out the final velocity with the information given.
