Homework Help: Centrifugal force

  1. Jan 29, 2009 #1
    If i could get some help on this that would be great.

    so.. A space station has an outer wall which acts as a floor at a radius of 180 meters. At what tangible speed must the space station rotate to simulate earths gravity. hint: assume a centrifugal force of 49 newtons is required on a mass of 5 kilograms.

    That was the question straight out of the homework and i am totally stumped.

    Welcome to PF.

    What is the equation for centrifugal force?

    And what is "tangible speed"?

    It couldn't be anything like "tangential speed" could it?
