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. Assume that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10 second before coming to rest.
Part A If its initial angular speed was 3890 rpm, find what is the magnitude of its angular deceleration?
Part B Determine how many revolutions did the centrifuge complete after being turned off?
