A 750 kg skier rides a 2830 m long lift to the top of a mountain. The lift makes an angle of 14.6˚ with the horizontal. What is the change in the skier’s gravitational potential energy?
2 answers
5.24 x 10^5 J
h = 2830sin14.6 = 713.4
mgh = 75*9.8*713.4 = 5.24e5 joules
mgh = 75*9.8*713.4 = 5.24e5 joules
