The tub of a washer is in a spin-dry cycle, running at a constant angular speed of 50 rad/s for a duration of 10s. After 10s, the lid is opened and the safety switch turns off the washer. The tub slows down to rest in 5s. Find the total angular displacement (for entire 15s) in (a) radians and (b) revolutions?

The tub of a clothes washer goes into its spin-dry cycle starting from rest and reaches an angular speed of 4.70 rev/s in 7.03 seconds. At this point, the person doing the laundry opens the lid, and a safety switch turns off the washer. The tub then slows to a stop in 20.04 seconds.

In a laundromat, during the spin-dry cycle of a washer, the rotating tub goes from rest to its maximum angular speed of 9.7 rev/s in 8.8 s. You lift the lid of the washer and notice that the tub decelerates and comes to a stop in 18.5 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.

The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.00 s, at which time it is turning at 4.00 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?
