: Can a bullet fall down vertically if shot from the back of an airplane with the same speed ?

Question

Let’s say that an airplane is going at 1200mph, and you have a gun that supposedly fires bullets at 1200mph, there is another airplane tailgating you and you decide to shoot it from a window in the back of the airplane, is it true that the bullet will not hit the airplane but instead fall down vertically with no force ?

This is purely hypothetical

Edit : I remember getting this idea when I was in 8th grade, about when 2 forces have the same intensity and opposite directions they get nulled ? I don’t remember that very well lol

Answer 1

yup, there’s a bunch of videos on youtube but with nerf guns and balls. i think there might be one with a cannon ball but i could be wrong.

edit: specifically with the plane scenario, yes that’s what would happen, unless the second plane is so near or low enough to fly into the bullet.

edit again: [soccerball, not cannonball](https://youtu.be/BLuI118nhzc)
