---- 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 10.7 s before coming to rest.
A) If its initial angular speed was 3830 rpm , what is the
magnitude of its angular deceleration?
B) How...

A fan rotating with an initial angular velocity of 1000
rev/min is switched off. In 2
seconds, the fan makes 10 revolutions.. Assuming the angular
acceleration is
constant, What is the angular speed after those 2
seconds?

A Ferris wheel rotates at an angular velocity of 2.3 rev/min.
Starting from rest, it reaches its operating speed with an average
angular acceleration of 0.030 rad/s2.
How long does it take the wheel to come up to operating
speed?
Through what angle (angular displacement) it rotates during
this time?

An electric fan is turned off, and its angular velocity
decreases uniformly from 570 rev/min to 250 rev/min in 3.00 s .
