The correct option is B Decrease the effect of impact by increasing the time to stop
In a high jump athletic event, the athletes are allowed to fall on a sand bed or cushioned bed to decrease the effect of impact by increasing the time to stop.
Impulse=Force×Δ t (Where,Δ t=time of impact
By increasing the impact time, the effect of force decreases and hence, the chances of injury decreases.
Hence, the correct answer is option (2).
