1. A skier has a mass of 80kg. He starts from rest and skis down a slope which drops 50m in height.
a) Calculate the amount of gravitational potential energy the
skier loses skiing down the slope.
b) What kinetic energy does he have at the bottom of the slope?
c) How fast is the traveling skier at the bottom?

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
