How fast does a bullet shot at a 90 degree angle hit the ground?

It is a common belief that a bullet fired at a 90 degree angle, perpendicular with the ground, will impact the surface simultaneously with a bullet dropped at the same altitude of the muzzle of the gun firing the projectile.
However, this theory cannot be confirmed due to several exterior ballistic variables such as ambient air density (temperature and humidity), air resistance, wind, Coriolis effect, Eotvos effect, and the ballistic coefficient of the projectile.
With all of these variables excluded, there is one thing that still disproves this common misconception.. That being the Magnus Effect.
Magnus Effect
The phenomenon whereby a spinning object in the course of a forward vector is acted upon by a perpendicular force caused by the object moving through a liquid or gas.
When a bullet is fired, the rifling in the barrel causes the projectile to spin in a clockwise motion (in most guns), this causes the bullet to veer from its forward vector due to water in the air (humidity).
Without wind, this phenomenon causes the bullet to rise and move to the right. This effect is very important to marksman because wind can force the projectile to ^roll^ or drop- a bullet subject to a downward-left force due to wind hitting the right side of the bullet.
This effect can be accurately predicted based on the rifle's turn rate, which can increase or decrease the effect because various rifles are made to fire with a turn rate of either 1:9 or 1:12, meaning the bullet will complete a revolution once every 9 inches, or 12.

How far does a bullet travel horizontally before gravity has an effect and takes over Is Newtons law correct that the bullet will hit the ground at the same time if it were simply dropped?
Gravity has an effect the instant the bullet leaves the barrel. The bullet starts to fall towards the earth at the same rate as the dropped bullet. However, (assuming the ground follows the curve of the earth, or you are shooting over water) the dropped bullet will hit the ground/water first. The reason is that the as the fired bullet falls the ground is receding away from it (the curve of the earth). The extreme example of this is: the bullet is fired fast enough that as it falls, the curve of the earth is 'falling' continuously away below it; we would say this bullet is now in orbit around the planet. However, if the ground you are shooting over is 'flat' (i.e. flat like a ruler, NOT following the curve of the earth) then: yes, the two bullets will hit the ground at the same time.
How fast can a bullet go in mph?
The speed that a bullet travels depends on the weight of the bullet. For example a bullet for a Magnum .357 made by Federal's American Eagle with a 158gr JSP load can travel at a speed of 1351 km/h.
Why would a bullet pierce a mirror without breaking it?
because it's fly's so fast that it doesnt have time to break it all...?
What is better at killing game light loads at hyper fast speed or heavier loads at slow speeds?
i believe this depends on the type of game you are hunting. for fast moving birds i would use faster loads for slower moving game such as turkeys heavy loads are the key due to better knock down power. this is just my opinion though That depends entirely on what the game is. If it is a heavy animal like a deer or larger then you need the penetration that only a heavy bullet will provide. A light, fast bullet will disintegrate near the surface and not penetrate to the vitals. If you are shooting a small varmit like a prarie dog, a fast, light bullet is adequate since you usually need to shoot from a considerable distance and need a flat shooting bullet, but you don't need any signifant penetraation to kill the animal.
How do monorails move so fast?
they use magnets so it doesn't hit the ground
How do you make mini maglev cars fast?
Put wires at a 45 degree angle upwards =)
How fast does a 357 bullet go?
They depends on the weather, the aiming degree. For instance if you're shooting upwards, the bullet will slow down until it starts falling down, which will increase the speed.
Why does a bullet ricochet sometimes when you shoot on a metal object with a gun and not always?
Lots of factors need to be taken into account: * What angle does the bullet strike the object? * What is the mass of the object? If small it will move and absorb the energy. * What is the bullet made of? Does the deformation absorb the energy? * Is the object firmly fixed or movable? * How fast is the bullet moving?
How fast can a bullet go?
rilly fast
If someone fires a 110 grain 38 caliber bullet straight up at 300 meters per s how high will the bullet rise how fast will it be going when it hits the ground?
If mechanical energy is conserved (like, if you did this on the Moon, where there is practically no air), when the bullet gets back to the ground it must have the same speed with which it started out. In practice, it will be less, due to air resistance.

it was fast
Can you prevent a bullet from hitting you by kicking it if someone shoots you?
This is impossible for a human to do. You would have to move at such a speed that the velocity of the bullet would no longer be a threat. Difficult to explain, however you would have to be able to move faster than the bullet. If you could move faster than the bullet, you would have to hit it from the correct angle to change its course. Almost like kicking it away from a 45 or 90 degree angle. If you have ever tried to swat a fly, you have to be faster than the fly. You must be faster than a bullet. Mythbusters, a television show on the Discovery Network in the US, has done this with trying to swat a bullet away. They used a robot to attempt to swat bullets and even to catch them in the teeth. There was just no way that the human body can react that fast. They were able to demonstrate that it is fully possible to catch an arrow shot at one, but even this was a pretty low success rate.
Why does a gun not recoil just as fast as the speed of the bullet?
because the recoil is when the bullet forces the gun back and so the bullet creates the recoil and so it can't make it go just as fast
