Predict the motion of a ski jumper (without friction)

Let's try to figure out the speed of a ski jumper as he leaves the ramp -- assuming that there is no friction.

  1. height of ramp H = 50 m
  2. length of ramp (along the surface) L = 115 m

What is the angle θ of the ramp?

If the skier starts from rest at the top of the ramp, how fast will he be moving when he leaves the ramp at the bottom?
