Step 1
- Initial angular speed, \( \omega_0 = 3890 \, \text{rpm} \). - Convert to revolutions per second: \[ \omega_0 = \frac{3890 \, \text{rev/min}}{60 \, \text{s/min}} = 64.8333 \, \text{rev/s} \] Show more…

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 10.2 s before coming to rest. (a) If its initial angular speed was 3850 rpm, what is the magnitude of its angular deceleration? (b) How many revolutions did the centrifuge complete after being turned off?

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 10.6 ss before coming to rest. If its initial angular speed was 3810 rpm , what is the magnitude of its angular deceleration? How many revolutions did the centrifuge complete after being turned off?
