A skier (68 kg) is on a ramp that is inclined at an angle of 20 degrees. The height of the ramp is 57 feet. The skier launches herself off the ramp with an initial velocity of 15 m/s. How far does the skier travel horizontally before landing on the snow?  How long is the skier airborne?  What forces are we neglecting here? What force is constant?
