Question

Do action and reaction act on the same body on different bodies explain your answer with the help of example write the total momentum of the gun and bullet after after firing

Answer 1

hello mate ,
____________

The action and reaction always work on different bodies .For example when we push a wall with our hand, the reaction of the wall is on our hand whereas action done by us is on the wall.
------------------
Total momentum will be the product of the combined mass of gun and bullet (M) and the velocity of the gun.

If the gun is at rest, the velocity would be zero.

Let the sum of momentum of bullet and gun be M.

So momentum = (mbullet +mgun ) x v = M x 0 = 0.
