A 64 kg skier starts from rest at height H = 27 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of θ = 23° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height h of his jump above the end of the ramp? (b) If he increased his weight by putting on a 10 kg backpack, what would h be?
