Question

with the help of a suitable diagram state and Prove the law of conservation of momentum and explain what is meant by recoiling of a gun starting from law of conservation of momentum obtain an expression for the recoil velocity

Answer 1

Answer:

Answer. When a bullet is fired from a gun, the gun recoils, i.e., moves in a direction opposite to the direction of motion of the bullet. The recoil velocity of the gun can be calculated from the principle of conservation of linear momentum. v2 = velocity of recoil of gun.

Law of conservation of linear momentum states that total momentum of the system is always conserved if no external force acts on an object or system of objects. Consider a collision between two balls wherein there occurs no energy losses during the collision.

Momentum of the two balls before collision,
