Question

While we catch a cricket ball, we catch it at the front and make the hands move with the ball backwards. Why is that?

• A. to increase the impulse on the hand
• B. to increase the time of contact, there by increase the force experienced by the hand
• C. to increase the time of contact, there by decrease the force experienced by the hand
• D. None of the above

Answer 1

Answer: (C)

to increase the time of contact, there by decrease the force experienced by the hand

The force which the ball exert on our hand times the duration of force is equal to the change in momentum .
$F\ast \Delta t=\Delta p$
So by increasing the duration we are reducing the effect of force on our hand.
