Vedclass · Answer

(C) 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 taken.By pulling his hands backwards,the goalkeeper increases the time $(\Delta t)$ taken to bring the ball to rest.Since the force is inversely proportional to time,increasing the time interval reduces the impact force exerted by the ball on the goalkeeper's hands,thereby preventing injury.
