Question
Part A A centituge is a common laboratory lestrument that separates components of diftering 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 continues to rotate with a constant angular deceleration for 11 0 s before coming to rest t its initial angular speed was 3810 rpen, what is the magnitude of its angular deceleration? My Answers Give Up Part B How many nevolutions did the centrifuge complete after being turnmed of? My Answers Give U 9 ommaExplanation / Answer
a) alpha = delta w / delta t
d = (3810 / 60) / 11
magnitude of angular deceleration = 5.77 rev/s2
b) n = (3810 / 60 )2 / (2 * 5.77)
No. of revolutions = 349.3 rev
