A hammer pile driver has a hammer with mass of 700 kilograms. It falls onto the top of a 140-kilogram pile from a 150 centimeter height, causing it to be buried 0.120 meters into the ground. If the impact is perfectly elastic, that is, e = 0, what is the average penetration resistance of the ground?
