Homework Statement

A typical laboratory centrifuge rotates at 4000 rpm. Test tubes have to be placed into a centrifuge very carefully because of the very large accelerations.What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation?

Homework Equations

No Clue

The Attempt at a Solution

I know that the 10cm we are given isn't a radius, so i have no idea where we are to start.

If you're in school, and have a textbook, i would suggest looking into Circular Motion and Gravitation, my textbook even has an example of the question your asking.

In not at school, my textbook doesn't have an example of it, i just need an equation for the work.

Your textbook would have an example. Your probably not looking in the right place. I'll give you a jumpstart. You need this equation to solve it. a=rw^2. you should be able to figure the rest out.
