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)=75cos(π/100x). Neglect friction and air resistance. Part A: Determine the skier's speed when he reaches point B on the smooth slope. Express your answer in feet per second to three significant figures

3. A toboggan and rider of total mass 90 kg travel down along the smooth slope defined by the equation y=0.08x². At the instant x - 10 m, the toboggan's speed is 5 m/s. At this point, determine the rate of increase in speed and the normal force which the slope exerts on the toboggan. Neglect the size of the toboggan and rider for the calculation. v=5m/s/ y=0.08.² 10 m
