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!
