Ans in revs.
The tub of a washer goes into its spin
dry cycle, starting from rest and reaching an
angular speed of 5 rev/s in 10.5 s . At this
point the person doing the laundry opens the
lid, and a safety switch turns off the washer.
The tub slows to rest in 5.6 s .
Through how many revolutions does the
tub turn? Assume constant angular accelera
tion while it is starting and stopping. Answer
in units of rev.
