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
(1) For the mass, u = 0, s = 5 m, a = g = 9.8 m/s^2
v^2 = u^2 + 2as
v^2 = 0 + 2(9.8)(5) = 98
v = sqrt(98) = 7 sqrt(2) m/s
Final momentum of ...
