A 55-kg skier starts from rest at the top of a ski jump, point A in Fig. 6–48, and travels down the ramp. (Assume the ski jump turns upward at point B and gives her a vertical component of velocity (at B) of 3.5 m/s .) If friction and air resistance can be neglected, (a) determine her speed vB when she reaches the horizontal end of the ramp at B. (b) Determine the distance s to where she strikes the ground at C.
