A 48 kg skier starts from rest at a height of H = 28 m above the end of the skijump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° 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?
m
(b) If he increased his weight by putting on a backpack, would h then be greater, less or, the same?
