1. Catching a cricket ball: When a fielder catches a cricket ball, he drags his hands backwards in order to increase the time taken by the ball to reduce its momentum to zero. This reduces the rate of change of momentum, thereby decreasing the force exerted on the hands by the ball.

 2. Seat belts in a car: When brakes are suddenly applied or a car crashes with an object, the seat belts increase the time taken to move forward, thereby decreasing the rate of change of momentum. Thus, the force of impact is reduced and fatal accidents can be prevented.

3. Athletes lands on sand: When an athlete lands from a height on a hard floor, he may hurt his feet because his feet comes to rest instantenously. So, a very large force is exerted by the floor on his feet. On the other hand, when he lands on sand, his feet pushes the sand for some distance, therefore the time duration in which his feet comes to rest increases. Thus, the force exerted on his feet decreases and he is saved from getting hurt.
