A ski jumper starts from rest from point A at the top of a hill that is a height h1above point B at
the bottom of the hill. The skier and skis have a combined mass of 80 kg. The skier slides down
the hill and then up a ramp and is launched into the air at point that is a height of 10 m above
the ground. The skier reaches point traveling at 42
