Establish Newton's third law of motion from the principle of conservation of linear momentum. A bullet is fired from a gun. Which one will possess greater momentum-gun or bullet?

Answer»

Solution :Before firing the bullet, both the gun and the bullet were at rest. Hence, INITIALLY total linear MOMENTUM was zero. After firing the bullet, the gun will have an EQUAL but OPPOSITE momentum to that of the bullet so as to conserve the total linear momentum of the SYSTEM.
