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.
