Homework Help: Revolutions per minute would a 15m diameter Ferris wheel

  1. Jul 3, 2003 #1
    How many revolutions per minute would a 15m diameter Ferris wheel need to make for the passengers to feel weightless at the topmost point?

    Re: Help

    FR = M * V^2 / R
    FG = M * g
    g = V^2 / R
    D = 2 * [pi] * R

    Live long and prosper.

    I Know That

    I have an answer but I need to check if it's correct. I got 11 revolutions per minute. Can anyone verify?

    Remarkably, I get the same thing. That's awfully fast but then I've never been on a "weightless" ferris wheel!
