Question:

Suppose the ski trail in Problem 31 is not friction less.

(a) Find the work done by gravity on the skier in this case.

(b) If the skier has a speed of 30 m/s at the bottom of the hill, what is the work done by friction on the skier?

Data From Problem 31

A skier of mass 110 kg travels down a friction less ski trail.

If the top of the trail is a height 200 m above the bottom, what is the work done by gravity on the skier?

Find the velocity of the skier when he reaches the bottom of the ski trail. Assume he starts from rest.
