Impulsive Force
The force that two colliding bodies exert on one another acts only for a short time, giving a brief but strong push. This force is called an impulsive force.
Examples
1.Long Jump:
The long jump pit is filled with sand to increase the reaction time when atlete land on it.This is to reduce the impulsive force acts on the leg of the athlete because impulsive force is inversely proportional to the reaction time.
2.High Jump:
During a high jump, a high jumper will land on a thick, soft mattress after the jump.This is to increase the reaction time and hence reduces the impulsive force acting on the high jumper.
Hope it helps

Answer:
The impulsive force is much stronger than any other force available at that point of time and acts on an object for a very short interval during collision or explosion. Examples are: ... When a batsman plays a shot for six, a force acts on a ball through a bat for short interval of time
