Rotational Frequency Homework: Find T to Calculate RPM

[apt8]

Homework Statement

A space stationwith a 120m diameter rotates to provide an artificial gravity of 3.00 m/s^2. Find the rotational frequency of the wheel (in reloutions per minute) that will produce this effect.

Homework Equations

VT=2pir

f=1/T

The Attempt at a Solution

VT=2pi60
VT=376.99
but i don't know how to get T (the period) by itself if i don't know the velocity.

Look up centripetal acceleration. You need to apply that to your problem.
