Question

A man falling on a cemented floor receives more injuries than falling on a sandy floor why

Answer 1

A man falling from a height receives more injury when he falls on cemented floor rather than when he falls on a heap of sand
---------------------------------------------------
Reason:
1 .If a man falls on a soft landing site like heap of sand, the man takes
a longer time to come to stop.
2. 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 monentum more gently.

3. If the man lands on hard ground like cement floor, then his momentum will be reduced to zero in,very short time .
4. The rate of change of momentum will be large due to,which a large opposing force,will act on the man.
5. This force,can lead to serious injuries to the man.

Answer 2

Sand decreases the momentum of the man more softly, becoming gentle and a man doesn't receive as many injuries as on a cemented floor.

Man falling on a sandy floor:

• Whether a man resembles a hill of sand on delicate handling, the man takes more time to stay away from.
• The pace of dynamic change is lower so a more modest power stops the fellow and he isn't harmed.
• Sand thusly diminishes the force of the man all the more delicately, becoming delicate.

Man falling on a concrete floor:

• If the man lands like a concrete floor on the hard earth, his energy, so a brief period, will be diminished to nothing.
• Because of which a solid inverse power can deal with the individual, the pace of shift in force is perfect.
• This power will make a man truly injured.
