Solve the following problem given below:
Problem: A skier of mass 111 kg travels down a frictionless ski trail.
Part I: If the top of the trail is a height 198 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.
m/s
Show the work for the calculation so I can understand what I'm doing. Thanks!
