Question

A 71kg skier with an initial speed of 18.22m/s coasts up a straight slope. The slope makes an angle of 41∘ relative to the horizontal, and once the skier reaches the top of the slope her altitude is 5.08m higher than it was at ground level. Find her final speed at the top, given that the coefficient of friction between her skis and the snow is 0.0800.
