Halliday, Resnick & Walker — Potential Energy and Conservation of Energy: Problem 22_M

A 60 kg skier starts from rest at height \( H = 20 \text{ m} \) above the end of a ski-jump ramp (Fig. 8.20) and leaves the ramp at angle \( \theta = 28^\circ \). 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 backpack, would \( h \) then be greater, less, or the same?
