Work and Energy problem, please help

  1. Nov 3, 2005 #1
    Tarzan and Jane, whose total mass is 140.0 kg, start their swing on a 6.0 m long vine when the vine is at an angle of 30.0° with the horizontal. At the bottom of the arc, Jane, whose mass is 50.0 kg, releases the vine. What is the maximum height at which Tarzan can land on a branch after his swing continues?

    I have tried to get this problem but i just seem to be pausing because i cant find the right information/formula to proceed.
    All help appreciated :smile:

    Energy is conserved. The energy of "Tarzan + Jane" at the starting point equals the energy they have at the bottom of the arc. When Jane lets go, Tarzan is left alone. But energy is still conserved. (You may find the problem easier than it looks. Try to do things with symbols; don't rush to plug in numbers.)
