Homework Help: physics

Posted by matt on Thursday, September 20, 2007 at 4:40pm.

the tub of a clothes washer goes into its spin-dry cycle starting from rest and reaches an angular speed of 6.50 rev/s in 7.85 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 15.07 seconds. Assuming a constant angular acceleration, while the tub is starting and stopping, how many revolutions does the tub turn during this 22.92 second interval?

oh god, could someone PLEASE help me with this question? please just dont tell me the answer, set me up with something comprehendable? any help is appreciated!!
