**1. The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 2.2 revolutions/s in 8.4 seconds. 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 9.5 seconds.**

through how many revolutions does the tub turn? assume constant angular acceleration while it is starting and stopping. answer in units of revolution.

i don't even know where to start really, besides finding the angular acceleration
