An 83 kilogram skier starts at rest 250 meter up the side of a mountain. The skier then travels down the slope until the ground levels out at the bottom. Friction can be ignored.
A) Evaluate the skier speed at the bottom of the slope?
B) After reaching the bottom of the slope, the skier collides with a 67 kilogram snowboarder and comes to a complete stop. If the snowboarder was initially at rest, calculate his velocity after the collision?
C) If the collision had been perfectly elastic, what mass would the snowboarder have needed to have a final velocity of 85 m/s?
