The strongest person in the world lifted th read end of his car a mass of 615 kg a verticle distance of .24 meters.
1) How much work did he do to life the car?
2) I can't lift 615 kg so I would use a jack to lift the car. One revolution of the jack handle lifts the car 1.8 meters. It takes 22 rounds to lift the rearend of the car a verticle disance of .24 meters. How much work did he do?
