A 5.00-kg crate is sitting on the ground at rest. An electric motor with an efficiency of 0.20 (20%) is used to raise a crate up by a height of 2.0 meters so that it has an upward velocity of 4.0 m/s as it reaches that height. Calculate the electrical energy consumed by the motor during this process.
