Homework Help: Tarzan swing force

  1. Oct 18, 2006 #1
    Hi, I have a question regarding forces and motion that I'm not sure on how to solve. I was wondering if anyone here could please show me. Thank you.

    Question: Tarzan weighs 820N and swings from a cliff at the end of a 20.0m vine that hangs from a high tree limb and initially makes an angle of 22.0 degrees with the vertical. Assume that an x-axis extends horizontally away from the cliff edge and a y-axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 760N. Just then, what is the force on him from the vine.

    Try summing up the forces and equate to mv^2/r

    Sounds like a trick question to me. :wink:
