Is My Calculation for Astronaut's Centripetal Acceleration Correct?

[BeckyStar678]

Homework Statement

Determine the rotation rate, in rev/s, required to give an astronaut a centripetal acc of 3g while in circular motion with radius 9.45 m.

Homework Equations

ac=v^2/r
i did 3g=v^2/9.45 and got 1.76
then i used T=2pie(r)/v, put in T=2pie(9.45)/1.76

The Attempt at a Solution

with doing what i did above i got 33.73. this doesn't seem right. 33 rev/s? that would be fast!

Double check your calculation for the velocity, it can't be right.

Also, make sure you check that your units work out in your calculations. If they don't come out to what you want, you've made a mistake somewhere.
