Question

Name and state the conservation principle on which the recoiling of a gun is based. Obtain the expression for the recoil velocity of the gun.

Answer 1

Its conservation of linear momentum 
it states that"if no external force acting on a body or object total momentum before collission is equal to total momentum after collission"

th expression of recoil velocity of the gun is

Force of the shell= -Force of the gun
    m1v1  =-m2v2

Answer 2

Answer:

Explanation:

ts conservation of linear momentum 

it states that"if no external force acting on a body or object total momentum before collission is equal to total momentum after collission"

th expression of recoil velocity of the gun is

Force of the shell= -Force of the gun

   m1v1  =-m2v2
