Assignment:
A pile is driven into the ground by a hammer of mass (M) 500Kg, dropped from a height of 4 meters. The mass (m) of the pile is 40Kg and the average resistance of the ground to penetration (Fr) is 45 kN.
1) Calculate the Velocity and the kinetic energy of the hammer prior to the impact with the pile.
2) Calculate the velocity and the kinetic energy of the hammer/pile combination immediately after impact.
3) Calculate the energy lost at impact.
4) Calculate the distance for which the pile penetrates the ground?
