Question

after firing a bullet from the gun, the recoil velocity of gun is __________than that of the bullet
​

Answer 1

Explanation:

This means that momentum of rifle = momentum of bullet after the bullet has been fired. Since the mass of the gun is much more compared to the mass of the bullet, its velocity is smaller than the velocity of the bullet hence heavier guns have less recoil than lighter guns.

Answer 2

Answer:

After firing the bullet, the bullet moves forward with a large momentum and the gun moves backward with an equal momentum.  

Let m and M be the masses of bullet and gun,respectively. If v and V are the velocities of the bullet and gun, respectively after the firing then:-  

0= mv+ MV

Therefore V=-mv/M  

The negative sign indicates that the gun moves in a direction to that of the BULLET.
