A washing machine turns on and starts from rest. The spin cycle starts and the machine steadily gains angular speed for 8 s at which point it is turning at 5 rev/s. The lid is then opened which shuts off the power to the machine and it slows down constantly over the course of 12 s. Through how many revolutions does the machine turn while it is in motion?
