If you fired an anti-tank rifle straight up, could the bullet leave the Earth?
If no, are there any guns that could fire a bullet into space?

answers:
daniel g say: Well, no gun today has a muzzle velocity of 17,000 MPH, needed to escape earths gravity.
Guns with the longest range are 25 miles at best, and that is not even half way out of the atmosphere.
Now the US navy has been playing with the rail gun, In tests, projectiles are out to 100 miles, and mach 7 velocity, that would stand a chance of putting a bullet into orbit.
Somewhere I did read of one specialized gun, R&D at Sandia labs shooting a projectile as fast as 10 miles per second,,I would think a man made meteorite and burn up in the atmosphere.
NASA has long been using air guns simulating micro meteorites.

Aquarius 1011 say: No, to both questions.
-
?*?*?*? say: Even a Rail gun could not do that!
You have failed Physics 101 In the school for half wits!

F say: I believe the big gun approach to space launches has been well researched and shown to be a non starter.
-
Gary say: Basic physics teaches that it will go straight back down.
-
Philipthepale say: Nope. There aren't any that have enough energy to overcome the drag and gravity.
-
USAFisnumber1 say: No. Escape velocity is roughly 7 miles per second. That is 5280 x 7 feet per second or roughly 36,000 feet per second. There is no gun made that can do that.

sirbobby98121 say: No. It does not have the needed velocity.

BBean say: First of all....wait...I`ll just start with NO so You won`t have to read the rest of my answer. I have fired an anti-tank recoilless rifle a long time ago in the usmc. The range wasn`t all that far then and just a guess that they are much more effective now. The projectiles are self propelled but not propelled enough to leave the influence of the earth. Besides that, the blast behind the barrel is not anything you want to stand behind and if aimed straight up doesn`t sound inviting to have that blast anywhere close to your feet. I have assumed you are talking about a device that can be carried by one person. The recoilless rifles of my days took two people to operate...one to hold and aim and one to prepare the projectile to fire. The rifle itself is not all that heavy. Surface to air missiles that can be fired by a single person are something for a present day soldier to answer so don`t be shocked if someone moves your question to the military section.

John say: No. Not anywhere near close. The projectile is losing both velocity and has the direct effect of gravity working against it. The missile would be lucky to make it a few miles up before dropping to Earth
-
L.N. say: There is a little thing called 'escape velocity' which is 36,700 ft/s. that you have to attain to leave the earth's gravitational field. That is roughly 10x faster than a high performance, high velocity rifle bullet. Not going to happen.
-
Gary say: Tanks are not dangerous and will never be banned.
No. Take high school physics and learn about exit velocity. Even a magnetically accelerated projectile from a rail gun will only go about 22% as fast as is necessary to escape Earth's gravity.
