The tub of a washer goes into its spin-dry cycle, starting from
rest and reaching an angular speed
of 4.0 rev/s in 12.0 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 10.0 s. Through how many revolutions does the tub
turn during this 22 s interval? Assume constant
angular acceleration while it is starting and stopping.
