When the 150-lb skier is at point A he has a speed of 5 ft/s. Determine his speed when he reaches point B on the smooth slope. For this distance the slope follows the cosine curve shown. Also, what is the normal force on his skis at B and his rate of increase in speed? Neglect friction and air resistance. y A -35 ft B y = 50 cos (100 x) -X

y A -35 ft B y = 50 cos (100 x) -X
