You are designing a ski jump ramp for the olympics. You need to calculate the vertical height (h) from the starting gate to the bottom of the ramp. The skiers push off hard with their ski poles at the start, just above the starting gate, so they typically have a speed of 2.0 m/s as they reach the gate. For safety, the skiers should have a speed of no more that 30.0 m/s when they reach the bottom of the ramp. You determine that for an 85.0 kg skier, friction and air resistance will do a total work
