A centrifuge in a medical laboratory rotates at an angular speed of 3800 rev/min. When switched off, it rotates through 46.0 revolutions before coming to rest. Find the constant angular acceleration of the centrifuge. in
The average speed while it comes to rest is 1900 rev/min. At that average rate, the centrifuge takes 46/1900 min, which is 14.53 seconds, to stop.
To get the angular deceleration rate, convert 3800 dev/mom to rad/s, and then divide by 14.53 s.
