Question: A skier of mass 104 kg travels down a frictionless ski trail.
Part I: If the top of the trail is a height 180 m above the bottom, what is the work done by gravity on the skier?
J
Part II: Find the velocity of the skier when he reaches the bottom of the ski trail. Assume he starts from rest.
