In a laundromat, during the spin-dry cycle of a washer, the rotating tub goes from rest to its maximum angular speed of 3.7 rev/s in 9.3 s. You lift the lid of the washer and notice that the tub decelerates and comes to a stop in 16.5 s. Assuming that the tub rotates with constant angular acceleration while it is starting and stopping, determine the total number of revolutions undergone by the tub during this entire time interval.
