A pile driver lifts a 450 kg weight and then lets it fall onto the end of a steel pipe that needs to be driven into the ground. A fall of 1.5 m drives the pipe in 45 cm.
What is the average force exerted on the pipe?

  1. the gravitational potential energy becomes work driving the pipe

    m g h = f d

    450 * g * 1.5 = f * .45
