| physics problem tough?
The tub within a washer goes into its spin cycle, starting from rest and reaching an angular speed of 11 rad/s in 9.0 s. At this point, the lid is opened, and a safety switch turns off the washer. The tub slows to rest in 16.0 s. Through how many revolutions does the tub turn? Assume constant angular acceleration while the machine is starting and stopping.
