A rifle gives backward kick on firing a bullet. before firing, both the bullet and the rifle are at rest and initial momentum of the system is zero. As soon as bullet is fired, it moves forward with a large velocity. in order to conserve momentum, the rifle moves backward with such a velocity that the final momentum of the system is zero.

Hey friend...
Here is your answer
__________________________________
Consider the example of air-filled balloon as described under the third law of motion.In this case, balloon and the air inside it form a system.Before releasing the balloon,the system was at rest and hence the initial momentum of the system was zero.As soon as the balloon is set free,air escapes out of it possesses momentum.To conserve momentum, the balloon moves in a direction opposite to that of air rushing out.
Three application of conservation of momentum in daily life
Air filled balloons
In the air-filled balloon, balloon and air inside form a kind of system.Initially when the system is at rest, so the momentum of the system is also zero.As soon as the balloon is set free air escapes out with some great velocity, balloon moves forward in the direction opposite to air rushing out.
The system of gun and bullet
Before firing both gun and bullet are at rest, therefore momentum of the system is zero.When the bullet is fired the bullet moves forward and gun recoils back.The mass of the gun is very large as compared to the mass of the bullet, therefore the recoils velocity is very small as compared the velocity of the bullet.
Motion of rockets and jet engines
Rockets and jet engines also work on the law of conservation of momentum.In these hot gases produced by burning of fuel rush out with a large momentum, Due to this, these machines gain an equal and opposite momentum.This momentum enables the rockets and jet engines with very high velocities.
