Question
Jane needs to swing across a river filled with man-eating crocodiles in order to rescue Tarzan from danger. However, she must swing into
a constant horizontal wind force, F, on a vine that is initially at an angle of 0 with the vertical (see Fig. P5.73). Use these values to solve
the problem: Jane's mass = 47.0 kg, Tarzan's mass = 80.0 kg, D = 50 m, F = 92 N, L = 40 m, and 0 = 56°.
