Work-Energy Theorem: Determine Distance for 73kg Skier w/ 4.2m/s

[Physicsgeeks1]

Homework Statement

A 73kg skier coasts up a hill inclined at 9.3 degree's to the horizontal. Friction is negligible. Use work-energy theorem to determine how far along the hill the skier slides before stopping, if the intial speed at the bottom is 4.2m/s


To find the distance I know i need w=Force applied x distance, but I can't find out how to get Force applied? I also just used W=change in EK to find work but is that correct?

Try drawing a free-body diagram for the skier. What are the forces acting on the skier, and in what direction are they?

Yes, that is the idea.
