A centrifuge takes 100.0s to spin up from rest to it's
final angular speed with constant acceleration. A point is located
10.0cm from the axis of rotation of the centrifuge moves with a
speed of 250.0m/s when the centrifuge is at full speed.
(a) What is the final angular speed?
(b) What is the average angular acceleration of the centrifuge as
it spins up?
(c) How many revolutions does the centrifuge make as it goes from
rest to it's final angular speed?

The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 3.7 rev/s in 6.3 s. At this point the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub slows to rest in 7.8 s. During the whole process of starting up and stopping, through how many revolutions does the tub turn? Assume constant angular acceleration while it is starting and stopping. Answer in...
