A 60 kg skier starts from rest at height H = 20 m abovethe end of a ski-jump ramp and leaves the ramp at angleu = 28. Neglect the effects of air resistance and assume the rampis frictionless. (a) What is the maximum height h of his jump abovethe end of the ramp? (b) If he increased his weight by putting on abackpack, would h then be greater, less, or the same?
