A 50.0-kg skier starting from rest travels 240 m down a hill
that has a 20.0° slope and a uniform surface. When the skier
reaches the bottom of the hill, her speed is 40 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?
