A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.5 before coming to rest.
If its initial angular speed was 3900 , what is the magnitude of its angular deceleration?
How many revolutions did the centrifuge complete after being turned off?
