When a person jumps from a tree to the ground what happens to the momentum of the person upon striking the ground ?

How does lightning strike the ground?

When an apple falls from a tree what happens to its gravitational potential energy just as it reaches the ground? After it strikes the ground?

A ball of mass 20 g falls from a height of 10 m and after striking the ground.It rebounds from the ground to a height of 8 m . (a) Calculate: (i)The kinetic energy of the ball just before striking the ground ,and (ii)The loss in kinetic energy of the ball on striking the ground,and (ii)the loss in kinetic energy of the ball on striking the ground. (b)What happens to the loss in kinetic energy in part(ii) ? Take g=10 m s^(-2) Neglect air friction .

A ball of mass 10 g falls from a height of y 5 m. It rebounds from the ground to a height of 4m. Find : (a) the initial potential energy of the ball, (b) the kinetic energy of the ball just before the ground. striking the ground, (c) the kinetic energy of the ball after striking the ground ,and (d) the loss in kinetic energy on striking the ground . Take g=9.8 m s^(-2) .

A body of mass m=2kg falls from a height h=10m from the ground level . What is the magnitude of total change in momentum of the body before it strikes the ground?

An object is projected horizontally from a top of the tower of height h. The line joining the point of projection and point of striking on the ground makes an angle 45^@ with ground, then with what velocity the object strikes the ground

A stone is dropped from a height h . It hits the ground with a certain momentum P . If the same stone is dropped from a height 100% more thanthe preyiious height, the momentum when it hits the ground will change by
