Explanation:
The cushioned bed or mat used in high jump competition serves the purpose of decreasing the impact of the athlete's landing. When the athlete jumps over the bar, he gains a significant amount of momentum due to his speed and upward thrust. The cushioned bed helps to decrease this momentum gradually, thereby reducing the impact of the landing.
Increase the time to stop:
By decreasing the momentum gradually, the cushioned bed increases the time taken for the athlete to come to a complete stop. This is important because if the athlete were to land on a hard surface, the sudden stop could cause injuries to his joints and muscles. By increasing the time taken to stop, the cushioned bed reduces the risk of injury.
Conclusion:
Thus, option C, i.e., "Increase the time to stop" is the correct answer. The cushioned bed in high jump competition is designed to decrease the impact of the athlete's landing by reducing his momentum gradually and increasing the time taken to stop.

In a high jump athletic event, the athletes are made to fall either on a cushioned bed or sand bed. This is to increase the time that the athletes fall to stop after making the jump. This decreases the rate of change of momentum and hence the force. As a result, the athlete does not get injured.
