Calculate Centrifugal Force to Simulate Earth's Gravity

[sebring741]

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 Earth's 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?
