Tarzan swing energy?
tarzan and jane, whose total mass is 130 kg, start their swing on a 5.0m long vine when the vine is at an angle of 30 with the horizontal. At the bottom of the arc,Jane, whose mass is 50 kg, releases the vine. What is the maximum height at which Tarzan can land on a branch after his swing continues? ( Hint: Treat Tarzan and jane s energey as seperate quantities.)
I m confused whether to use cos or sin to find the real length of the vine at 30*, calculations and answer would be much appreciated.

ho = L(1-cos 60°) = 5*(1-0.5) = 2.5 m
Hmax = ho = 2.5 m
