When catching cricket ball, we pull our hands back. why?

To reduce the force exerted on the hands
Explanation:
When a person moves his hand backwards while catching a ball, he actually increases the time of the impact of the force.
Or F
May this answer helps.😁
Frankly, We do it not to miss the catch. XD
For the Actual Reason, See Below.
Explanation:
When the ball comes towards you, it surely has an velocity (lets
say
stops, the velocity becomes zero, so as the momentum.
So, Change In Momentum or Impluse =
So, This Change is huge, as the initial momentum is huge.
And, The second issue is the Time of Impact.
It is way way way too small.
So, The Force Applied by The Ball =
and, you must know that, When We divide Something huge by Something very small (Imagine
So, Action force of the ball is very huge.
According to the Newton's Third Law,
So, The Reaction force will be huge too and act on the ball, in opposite direction, which makes the ball slip out of the hand.
Just to stop this, We pull our hands back, which increases the Time Of Impact, which lessens the Force (
Hence Explained, But sloppily (Hehe).
