The tub of a washer into it’s spin-dry cycle

Reference no: EM13659697

The tub of a washer into it’s spin-dry cycle, starting from rest and reaching an angular speed of 5.0 rev/s in 8.0 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 12.0 s. During how many revolutions does the tub turn in the entire 20 second interval? Suppose that the angular acceleration is constant while it is starting and stopping.
