## Homework Statement

A space station has a radius of 200 meters. An astronaut has a mass of 55 kilograms and the station rotates at 1.5 rev/min. What is the period of rotation for the station?

## Homework Equations

$$\tau$$=2$$\pi$$r/v
a=v2/r
Fg=mg
FNET=ma

## The Attempt at a Solution

I think the FNET equation is Fsp=ma and I'm pretty sure you have to solve for $$\tau$$ but in order to do that I need to solve for a. How do I either find a velocity or acceleration to do this?
