Question

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 before striking the pipe drives the pipe in 35 cm.​

Answer 1

Explanation:

the gravitational potential energy becomes work driving the pipe

m g h = f d

450 * g * 1.5 = f * .45
