The pile P has a mass of 800 kg and is being driven into loose sand using the 300-kg hammer C which is dropped a distance of 0.5 m from the top of the pile. Determine the distance the pile is driven into the sand after one blow if the sand offers a frictional resistance against the pile of 18 kN. The coefficient of restitution between the hammer and the pile is e=0.1. Neglect the impulses due to the weights of the pile and hammer and the impulse due to the sand during the impact. 0.5 m
