A 121.79-kg skier starts with an initial speed of 24.77 m/s and coasts up a H=8.92-m-high rise as shown in the figure. If her final speed at the top is 10.21 m/s, what is the angle of the slope in unit of degrees? Assume the coefficient of friction between her skis and the snow is 0.12 (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.) Use g = 10 m/s2
