A 2.10 x 103 - kg pile driver is used to drive a steel I - beam
into the ground. The pile driver falls 5.00 m before coming
into contact with the top of the beam, and it drives the beam
12.0 cm farther into the ground as it comes to rest. Using energy
considerations, calculate the average force the beam exerts on
the pile driver while the pile driver is brought to rest.
