A 70.0 kg skier rides a 2700 m long lift to the top of a mountain. The lift makes an angle of 14.3° with the horizontal. What is the change in the skier's gravitational potential energy?

2. Relevant equations

3. The attempt at a solution

mg cos(?) * (h0 - hf)

again, not sure why this formula doesnot work.
