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 24.5 s before coming to rest. (a) If its initial angular speed was 4610 rpm, what is the magnitude of its angular deceleration? answer in rev/s2 (b) How many revolutions did the centrifuge complete after being turned off? answer in rev

Explanation / Answer

Angular speed = 4610 rpm=4610/60=76.834 rev/s
A)=>Angular retardation=76.834/24.5=3.1360 rev/s^2

B)No of revolution of centrfugal pump before coming to rest
=76.834*24.5 = 1882.43

Calculations maybe faulty, logic is correct.

Hope this helps :)
