Problem 5 in internet homework M5 H\"? A describes a pile driver falling onto a beam. The forces acting on the pile driver are gravitational force exerted by the earth and normal force exerted by the beam. Using the distance values given in your version of the problem, determine the following (3) Over what vertical distance does the gravitational force do work on the pile driver? (b) Over what vertical distance does the beam's normal force do work on the pile driver? A LOUDkg pile driver is used to drive a steel Ibeam into the ground. The pile driver falls 3.40 m before coming into contact with the top of the beam,r and it drives the beam 16.0 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. magnitude f N direction J
