How do you solve this problem?
How fast (in rpm) must a centrifuge rotate if a particle 9.00cm from the axis of rotation is to experience an acceleration of 115,000 g's?

115000g=w^2 * r
you know g, r, solve for w (in radians per second). Convert that to rpm 
I am confused, can someone show me how to work this problem? I really need help!

How do you work this problem out??
