(a) What is the maximum height h the skier can reach after jumping off the ramp?
(b) If the skier had increased his weight by taking a bag on his back, would the ℎ height be higher, less or remain the same? Explain.
(c) If there were air resistance, would the height of h increase, decrease or remain the same? Please explain.
(d) Calculate what would be h if the length of the path above the jump point of the ramp (i.e. the part above the dashed line according to the figure) were d = 50 ? and the kinetic coefficient of friction uk = 0.2.
