Question

The tub within a washer goes into its spin
cycle, starting from rest and reaching an angular speed of 13 π rad/s in 6.9 s. At this
point, the lid is opened, and a safety switch
turns off the washer. The tub slows to rest in
12.0 s.
Through how many revolutions does the
tub turn? Assume constant angular acceleration while the machine is starting and stop-
