?A 1,800-kg pile driver is used to drive a steel I-beam into the
ground. The pile driver falls 3.60 m before coming into contact
with the top of the beam, and it drives the beam 14.2 cm farther

calculate the average force the beam exerts on the pile driver
while the pile driver is brought to rest.
