1. The problem statement, all variables and given/known data 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? 2. Relevant equations No Clue 3. The attempt at a solution I know that the 10cm we are given isnt a radius, so i have no idea where we are to start.
