Acentrifuge 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 10.0s before coming to rest.
part a
if its initial angular speed was 3890rpm , what is the magnitude of its angular deceleration? (|? | in revs/s^2 )
part b
how many revolutions did the centrifuge complete after being turned off?
