Question

A typical laboratory centrifuge rotates at 4200 rpm. Test tubes have to be placed into a centrifuge very carefully because of the very large accelerations.

i) What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation?

ii) 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 2.0-ms-long encounter with a hard floor?
