The skier starts at a snow covered slope which is inclined 20 degrees above the horizontal. The skier has a mass of 100kg. The coefficient of static friction is 0.25 and the coefficient of kinetic friction is 0.12 between the skier and the snow. He goes down the 20 meter long incline of the bunny slope.

a. How fast are is he going at the bottom?

b. How long does it take them to go the 30 meters?
