# Fly to the sky

Level pending

Ski jumping is a sport in which skiers go down a take-off ramp, jump and attempt to land as far as possible down the hill below. If the length and height of the ramp are $$90$$ m and $$50$$ m, respectively, and the weight of skier is $$100$$ kg, then how much potential energy can the skier use? (The magnitude of the gravitational acceleration is 9.8 m/$$s^2$$.)
