The tub of a washer goes into its spin-dry
cycle, starting from rest and reaching an angular speed of 2.9 rev/s in 8.5 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 11.6 s.
Through how many revolutions does the
tub turn? Assume constant angular acceleration while it is starting and stopping.
