##### Reference no: EM13216861

When the power to an electric motor is turned on, the motor reaches its rated speed of 3300 rpm in 6 s, and when the power is turned off, the motor coasts to rest in 80 s. Assume uniformly accelerated motion. Determine the number of revolutions that the motor executes in a) reaching its rated speed, b) coasting to rest.
