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 (in m/s) 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.

[Impulse and momentum: Impact]
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 (in m/s) 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.
