A B y(x) 35 ft x When the 150-lb skier is at point A he has a speed of 5 ft/s. When the skier reaches point B on the smooth slope, the slope follows the cosine curve shown in (Figure 1). Suppose that y(x) = 55 cos Neglect friction and air resistance. (100%) Determine the skier's speed when he reaches point B on the smooth slope.
