1. The problem statement, all variables and given/known data Tarzan is in the path of a pack of stampeding elephants when Jane swings in to the rescue on a rope vine, hauling him off to safety. The length of the vine is 27 m, and Jane starts her swing with the rope horizontal. If Jane's mass is 56 kg, and Tarzan's mass is 91 kg, to what height above the ground will the pair swing after she rescues him? (Assume the rope is vertical when she grabs him.) 2. Relevant equations (1/2)mv^2=KE mgh=PE 3. The attempt at a solution I know that this is an inelastic collision, but I do not know how to set up the problem, I was thinking along the lines of: (1/2)mv^2=mgh after finding the velocity of Jane, but I dont know how to do that. Help?
