A skier is traveling at a speed of 35.7 m/s when she reaches the base of a frictionless ski hill. This hill makes an angle of 11° with the horizontal. She then coasts up the hill as far as possible. There is friction with μK = 0.10 between the skis and the snow. What height (measured vertically above the base of the hill) does she reach?
ΔE = 0
½ mv² - μ m g (h/sin θ) cos θ - m g h = 0
½ 35.7² - 0.1 * 9.8 * (h/sin 11°) cos 11° - 9.8 h = 0
h = 42.9362 m
