A pile driver drives a pile into the ground. This means that a mass of 1000kg is lifted through 5m and released to fall freely on the pile.
a) Determine the impulse produced by the pile-engine.
b) If it is assumed that the impulse lasts for 1/100 s, find the force on the pile.
c) If 80% of the energy is effectively used in the process, calculate the distance through which the pile will proceed for each blow.
