Centripetal Force, very simple.

  1. Nov 19, 2008 #1
    1. The problem statement, all variables and given/known data

    A man hanging upside down is holding a partner who weighs 475 N. Assume that the
    partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 4.00 m/s,
    what force must the man apply to his partner in the straight-down position?

    2. Relevant equations

    F=mv^2/r

    3. The attempt at a solution
    I just plugged in the numbers and got 1,169. Is it correct?

    Hi nothing4me! :smile:

    That's the correct centripetal force, but you still have to deal with the gravitational force. :wink:
