When turning on a motor, it reaches a nominal speed of 2,500 rpm in a time of 12 s; when the motor is turned off it takes 42 s to come to a complete stop. If we start from the angular motion is uniformly accelerated, determine the number of revolutions that performs the motor to reach the rated speed and then to stop.
