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 initial speed of the pile just after it is struck by the hammer. 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.
