Calculating g-force

  1. Nov 28, 2014 #1
    1. The problem statement, all variables and given/known data
    i have a question where i need to calculate the g's experienced by people on a carnival ride called the "gravitron" the ride simply spins riders around in a circle. i have calculated Vc(centripetal velocity) to be 20.9439m/s and the radius is 3.0 meters... how would i calculate the g's experienced by the riders?

    2. Relevant equations
    i think i would use V^2/r then divide that by earths gravity(9.81m/s^2)

    3. The attempt at a solution
    the g-force i got was around 14g's but that would probably kill you??...

    Yes, you can find out how many g's are experienced by dividing the centripetal acceleration by g.
    But post the full text of the problem. Otherwise we can't tell if your intermediate results are correct or not.
