Question

Prove the law of conservation of Momentum. Use it to find the recoil velocity of a gun when a bullet is fired from it.

Answer 1

Answer:

Kinetic energy..........

Answer 2

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. ... Therefore, linear momentum before firing equal to zero.
