Physics
A typical laboratory centrifuge rotates at 4200rpm. Test tubes have to be placed into a centrifuge very carefully because of the very large accelerations.
1. What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation?
Express your answer with the appropriate units.
2. For comparison, what is the magnitude of the acceleration a test tube would experience if dropped from a height of 1.0 m and stopped in a 1.7-ms-long encounter with a hard floor?
Express your answer with the appropriate units.
