As soon as the is set free air escapes out with some great velocity, moves forward in the direction ⬇️⬆️ (opposite) to air rushing out. Before firing both and bullet are at rest, therefore momentum of the system is 0 .
during projectile motion and where air resistance is negligible, momentum is conserved in the horizontal direction because horizontal forces are 0 and momentum is unchanged. But along the vertical direction, the net vertical force is not zero and the momentum of the projectile is not conserved.
HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
