Hello friend!
Here's ur answer!
When a person falls from a certain height on a hard concrete floor than on a sandy surface he/she is prone to more more serious injuries as when he falls on the hard floor, he/ she comes to rest almost instantaneously so the floor exerts a large force on the person and gets injured. But if he/she falls on sand or carpet, the time duration in which he/she comes to rest increases and so the carpet or sand exerts a less force on the person and he is not injured.

Answer:
Explanation:
When jump on heap of sand.
If a man falls on a soft landing site like heap of sand, the man takes a longer time to come to stop. The rate of change of momentum is less due to which a smaller stopping force acts on the man and he does not get hurt. Thus, Sand, being soft reduces, the man's momentum more gently.
When jump on heap of sand.
If the man lands on hard ground like cement floor, then his momentum will be reduced to zero in, very short time. The rate of change of momentum will be large due to, which a large opposing force,will act on the man. This force, can lead to serious injuries to the man.
