What would happen if a fielder stops a fast-moving ball suddenly? Justify your answer.

(N/A) When a fielder stops a fast-moving ball suddenly,the velocity of the ball decreases to $0$ in a very short interval of time.
According to Newton's second law of motion,the force applied is directly proportional to the rate of change of momentum,given by $F = \frac{m(v - u)}{t}$.
Since the time interval $(t)$ is very small,the rate of change of momentum is very high.
This requires the fielder to apply a large impulsive force to stop the ball.
Consequently,the ball exerts an equal and opposite reaction force on the fielder's hands,which may cause injury to the palm.
