If a hammer has mass 500kg and it falls freely fom rest a height of 5m on to a pile of mass 1500kg. They then move together as the pile is driven 0.12m into the ground. The intial velocity of the hammer is 10m/s. The velocity after impact is 2.5m/s. The total Kinetic Energy of the pile and hammer is 6250J. The total Potential Energy of the pile and hammer is 2400J.

if you know the mass so f=m*g comes into effect and the acceleration =9.8m/s2 from the gravitational pull coupled with weight =m*g it all depends on the density and mass of the pile of muck (for want of a better word) it landed in. And ive been drinking tetleys so thats not a bad reply.

Each time the hammer strikes the pile the resistance will increase, if the pile hits bedrock or any change in resistance this will alter the answer too.

It is greatly dependant on an unknown variable - via - the density of the ground.

You need to know the resistance characteristic of the soil into which it is driven.

Tensile strength of the soil material and compaction level.
