To simulate the extreme accelerations during launch, astronauts train in a large centrifuge. If the centrifuge diameter is 13.5m , what should be its rotation period to produce a centripetal acceleration of
If the centrifuge diameter is 13.5m , what should be its rotation period to produce a centripetal acceleration of 4 g?

Given:
r = 13.5[m]
a = 4g, where g=9.8[m/s^2]
Use:
a =  r ω^2
Where ω is the angular velocity (in radian per second).
Find: ω
Use this to find the rotation period.

Graham, what would be the formula i would use for the rotation period? i tried v=(2*pi*R)/T and got T to be 50 but my answer is still coming out wrong.
