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.

A wooden pile of mass m=3kg is driven into the driven into the ground by suceessive blows from a hammer of mass M=10kg falling from a height h=3 m on the head of the pile. If under the action of a single blow the pile penetrates a distance delta = 5 cm, determine the resistance R to penetration.

A body of mass 0.02 kg falls from a height of 5 metre into a pile of sand. The body penetrates the sand a distance of 5 cm before stoping. What force has the sand exerted on the body ?

A body of mass 0.02 kg falls from a height of 5 metre into a pile of sand. The body penetrates the sand a distance of 5 cm before stoping. What force has the sand exerted on the body ?

A weight of 200 kg is repeatedly dropped freely from a height of 10 m, on the head of a pole of mass 50 kg, to push it into the ground. For every impact, the pole penetrates 7 cm into the ground. Find the average resistance of the ground.

A body of mass m falls from a height h_1 and rises to a height h_2 . The magnitude of the change in momentum during the impact with the ground.

A block of mass m is dropped from height h above the ground. Find out the speed of the block when it reaches the ground.
