Homework Help: Circular motion space station question

  1. Feb 5, 2010 #1
    could some one explain where am i wrong?

    A proposed space station includes living quarters in a circular ring 53.5 m in diameter. At what angular speed should the ring rotate so the occupants feel that they have the same weight as they do on Earth?

    in such a station there is a centr. force mv^2/r.
    it equals mg since i want them to feel like on earth.
    then i play with the equation, lose m make v=wr.
    and find w.

    Have you used diameter instead of radius? The method seems fine.
    What result did you get?

    v^2/r has to be equal to g then you can work from there
