A hainmer of mass Mkg falls from a height h meter upon the top of an inelastic pile of mass m kg and drive it into the groung a sistance x meter. Find the resistance of the ground ehen it is assumed to be constant. Find also the time during which the lile is in motion and the kinetic energy lost at the impact.

Answer

`"["(M+m)g+(M^(2)gh)/((M+m)x),((M+m)x)/(M)sqrt(2/(gh))"]"`
