A motorcyclist runs out of gas on a level road 250 m from the gas station. She pushes the 220-kg motorcycle with a constant force of 150 N. How much work does she do?   For the motorcycle of the previous problem, if it was moving with a kinetic energy equal to the work done on it, how fast would it move?
