If i point a gun with the highest bullet speed to the sky on a plane, will the bullet reach space?

Where does space begin? Gravity will always act on a bullet and lower its speed with time. Firing a gun from a plane will give you a altitude advantage but the bullet can only achieve a finite altitude and it will be short of that required to reach "space"

Gunpowder includes its own Oxygen. Nitrate (NO3) is the Nitro in nitrocellulose. the priority with the vacuum of area is that if the loaded cartridge became made in a pressurized environment, exposing it to a vacuum could reason the bullet to be pushed out via purely the air tension interior. yet whilst the cartridge became loaded in a vacuum and then fired in area the bullet could commute for ever and ever till the gravitational pull of a few thing affected it. case in point in case you progression an merchandise in area a ways far off from any planet this is going to save going till a heavenly physique variations that circulation. This is going for any speed from a million mile and hour to hundreds of MPH. area has count in it, its no longer an entire void. The image voltaic wind is an occasion. yet its no longer close to as dense as our environment. It’s the resistance of our environment that slows a bullet down. So in area that bullet could commute huge distances in the previous it slowed in any respect. additionally with out gravity or environment to slow it down the bullet could flow swifter than on the earth.

If it is send with escape velocity then yes it will reach space.
