A 50.0-kg skier starting from rest travels 200 m down a hill that has a 20.0^o slope and a uniform surface. When the skier reaches the bottom of the hill, her speed is 30.0 m/s.

(a) How much work is done by friction as the skier comes down the hill?

(b) What is the magnitude of the friction force if the skier travels directly down the hill?
