1. The problem statement, all variables and given/known data Tarzan (mass 98.3552) stands on a 4.45 m cliff next to a river. He grabs a vine of length 30.1 m whose point of support is directly above Jane (mass 57.5336). He grabs Jane at the bottom of his swing and has just enough speed to make it to the other side. How long does the rescue take? 2. Relevant equations I assume some kinematics. 3. The attempt at a solution I already solved the other two parts (Tarzans speed at bottom (9.339 m/s)and height of other side (1.7714 m). I triedd d = .5at^2 for both sides of the swing (down and back up) but didn't expect it to be right. It probably has something to do with harmonic motion?
