The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 10.0 s, at which time it is turning at 6.00 rev/s. at this point, the lid of the washing machine is opened, and a safety switch turns it off. the tub then smoothly slows to rest in 13.0 s. through how many revolutions does the tub rotate while it is in motion?
