Q5 (? .s): When the 75 kg skier is at point A, she has a speed of 1.5m/s. Neglecting friction and air resistance, and using a cosine curve for the slope (as shown in the figure): (a) Determine her speed when she reaches point B on the smooth slope. (b) What is the normal force on her skis at B, and her rate of increase in speed? A 12 m B y = 20 cos (30 x)
