The tub of a washer goes into its spin-dry cycle, starting fromrest and reaching an angular speed of 4.0 rev/s in 8.0 s. At thispoint, the person doing the laundry opens the lid, and a safetyswitch turns off the washer. The tub slows to rest in 14.0 s.Through how many revolutions does the tub turn during this 22 sinterval? Assume constant angular acceleration while it is startingand stopping.
1 rev
