Centripital Motion question

  1. Nov 17, 2004 #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 of the trip?

    Please help me with that question, as I dont even know where to start.

    Consider the forces on a person at the top of the wheel.

    Can someone please give me a bit more information because I;m confused at what to do when I'm only given the radius.

    Actually after doing a few more problems like this, I think I've gotten the hang of it. For this question I got an answer of 11 revolutions per minute. Is this correct?
