Question

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 26.2 s before coming to rest. (a) If its initial angular speed was 3110 rpm, what is the magnitude of its angular deceleration? rev/s2 (b) How many revolutions did the centrifuge complete after being turned off? rev

Explanation / Answer

=3110/60=311/6

=/t =311/(6*26.2)=1.97 rev/s2

b)=t-1/2t2=681.88 rev
