Vedclass · Accepted Answer

The momentum of the ball was reduced to zero in a very short interval of time,resulting in a large impulsive force.

Vedclass · Answer

(B) According to Newton's second law of motion,the force exerted is given by $F = \frac{\Delta p}{\Delta t}$,where $\Delta p$ is the change in momentum and $\Delta t$ is the time interval.When the goalkeeper stops a fast-moving ball,the momentum of the ball changes from its initial value to zero.Since the time interval $\Delta t$ is very small,the force $F$ exerted by the ball on the goalkeeper's hands becomes very large.This large force causes the injury to the goalkeeper's hands.

While playing football,the goalkeeper did not get sufficient time to stop a fast ball shot towards him. Why did he hurt his hand while doing so?
