A rope exerts a 274N force on an 80kg skier up along a hill inclined 12 degrees. A frictional force of 100N opposed the motion. If the skier starts from rest, what is her speed after travelling 100m?
Fnet = ma
274-100 = 80a
Assuming a start from rest
v^ = 2a 100 with the a you found.
Not sure what the 12o incline is about.
