Question 2. The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.0 seconds, at which time it is turning at 5 rev/s. At this point the person who is doing laundry opens the lid of the machine and a safety switch turns the machine off, smoothly slowing the tub to rest. It takes 12 seconds after opening the lid for the tub to stop. Through how many rotations does the tub turn while it is in motion?
