A snow skier is skiing across a flat plain with a velocity of 3.5 m/s. Without knowing because the snowfall is so thick he skis off a cliff with vertical drop of 58m. The skiers mass with skis and all is 92kg. What is the initial potential energy of the skier the moment before he goes off the cliff? What is the final vertical velocity of the skier right before he hits the ground?
