• A. Increase the effect of impact by decreasing the time to stop
• B. Decrease the effect of impact by increasing the time to stop
• C. Decrease the effect of impact by decreasing the time to stop
• D. Increase the effect of impact by increasing the time to stop

Answer 1

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.
$Impulse=Force\times \Delta t(Where,\Delta t=\text{time of impact}$
By increasing the impact time, the effect of force decreases and hence, the chances of injury decreases.
Hence, the correct answer is option (2).
