Problem 1- A 70 kg skier starts to slide from H = 25 m above the jumping ramp as shown in the figure and jumps off the ramp at an angle of 0 = 30° . If the ramp is frictionless and the effect of air resistance is neglected, (a) What is the maximum height k that the skier can reach after jumping off the ramp? (b) If the skier had increased his weight by putting on a backpack, woulf the height h be higher, lower or remain the same? Explain. (c) If there was air resistance, would the height h be higher, lower or remain the same? Explain. (d) What would h be if the length of the path above the jump point of the ramp (i.e, the part of the path above the dashed line according to the figure) were d = 50 m and the coefficient of the kinetic friction uz = 0.2 ?
