Centripedal force velocity question. need help!

  1. Dec 14, 2008 #1
    Tarzan is standing on a limb of a tree, holding onto a vine whose length is 30 m. Seeing Jane on a branch of another tree, Tarzan decides to use the vine to swing oer to Jane's branch. The vine he is holding onto makes an angle of 37 degrees with the horizontal. What will be Tarzan's velocity at the bottom of his swing toward Jane?

    the question doesnt give you a mass, i have no clue how to do it
    any help is appreciated thanks!!

    You don't need to know the mass. (Just call it "m" and continue.)

    Hint: What's conserved?

    what is conserved?? im guessing you mean energy. so if i use the equation final energy = initial energy with all the mass canceling out and then i find the height of tarzan in the middle of his swing in relation to tarzan at the beginning of his swing, i should be able to calculate the final velocity, correct?

    Sounds to me like you've got it.
