why does a fall on a hard concrete floor hurt more than a fall on a sandy surface . please give the answer using newton 2 nd law
Answers
Answer:
When you jump onto the concrete surface, your feet are brought to rest almost instantaneously because the rate of change of momentum is very high. Hence, you get injured due to a large force on your body on account of the hard floor.
But, when you jump on sand, you come to rest in a longer period of time. So, the change in momentum takes place in longer interval of time. Hence, a small force is exerted on your body and you don’t get injured
Step-by-step explanation:
Answer:
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
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.
