Ok, so this guy who I am really friendly with says that getting hit by a 9mm is like getting hit by a hammer. I believe that, but another one of my friends say that getting hit by a ak-47 is like getting hit by a truck. Is that true? I know that a 7.62 transfers around 3,200~3,700 joules but I don't think it is like getting hit by a truck.
not sure, why dont you try yourself...
Your friends get shot alot eh?
Sure, I'll need a volunteer though.... I don't want to get shot. Would you please come up?InfectiousShadow wrote:

what kind of nine rifle hand gun, how many grains per bullet what type of round talon, hollow point or full metal jacket
I'm sure the results of self-testing would be fruitfull.
As for the truck comparison, it would depend on the speed of the truck and and what range would be getting shot from, so it can vary. A 7.62mm round will definitely knock you down though.

Yeah.. I was thinking about that too. Maybe the truck is going a around 35~45 MPH. Does anybody know what is equivalent of getting hit by a Barret m107 with a AP round?SplinterStrike wrote:

well a 92fs like mine with fmj will hurt like hell and for the rifle it has a higher muzzle velocity so it will hurt watch spike tv once in a while it shows a rifle round going through an apple or something. anyways thats what a bullet does when it hits human flesh. also watch mythbusters i think they shot some pigs or something like that with different guns and ammo not sure
No, it's not. If it was, the shooter would go flying back several feet based on the law "every action has an equal and opposite reaction". In other words, as much energy that goes into the bullet would also be transferred into the gun and the shooter. Considering that the shooter does not go flying several feet, like someone hit by a truck going 35-40, you can conclude that it's not equivalent.thtthht wrote:

As for the 7.62, using the same principal, the round itself doesn't knock the target off their feet otherwise the shooter would also be knocked down by the recoil. The target would likely have been knocked down by the wounds recieved rather than by the bullet iteslf.
I do watch mythbusters. They did shoot a pig and "buster" several times and I saw the damage. However, I still want to know if a 7.62 can hit your like a truck coming at 35~45 MPH.wachtler83 wrote:

Your friends may be a little off. I have never been shot but I do a lot of shooting and can tell you what it does to certain materials. 7.62 x 39mm will punch threw thin steel a bought 8 inches tall, by 4 inches wide,2 millimeters thick and cause it to be pushed back a bought a foot with a clean hole in it. A 9mm will not penetrate but will leave a nice dent and knock it over. So based on this id say 9mm would be innately like a extremely hard hammer hit and 7.62 x 39mm would be innately like a extremely hard sledgehammer hit.
Not a truck. But don’t take my word on this. This is just my experience leading me to a simple speculation.

comparing an object that small to an object that big might not be too accurate. If you get hit by a truck doing 45 you are completely dead no matter how it hits you. It will smash your whole body in. a standard round from an AK can of course easily knock you over from that amount of force, but depending on where it hits you you will live.thtthht wrote:

The wound will slowly bring you down to your knees, but the bullet cannot knock you down instantly.Kamikaze17 wrote:

Man, I shot an AK-47 out at my friends house that thing rocked! It was at a junk lot, we were shooting at CO2 cans and stuff. Good times, I busted a hole in a cooler too haha.
oh then no it cant like kamikaze17 said a couple of posts up cant happen do to every action has an equal and opposite reactionthtthht wrote:

the mythbusters thing was to see if hollywood style gun deaths (nine mile flybacks etc.) were possible. they proved that they weren't, and the only thing to actually make the pig and buster move was a shotgun or something like that.wachtler83 wrote:

so, although the energy transferred may (or may not be) be the same, it will not be like getting hit by a truck.
this is simple physics at this point, as with a truck, the impact is spread throughout your body, which dissipates the energy.
with a bullet, it will keep the majority of the energy centralized, which means that it will pass through you, assuming its not a shitty hollow-point or something meant to stop within you.
as we can figure out from the story of the guy who fell a mile and lived, thats not necessarily true. not to mention i know a few people who have been in that situation.comparing an object that small to an object that big might not be too accurate. If you get hit by a truck doing 45 you are completely dead no matter how it hits you. It will smash your whole body in. a standard round from an AK can of course easily knock you over from that amount of force, but depending on where it hits you you will live.
in fact, just this summer my best friend got hit by a truck that wasn't really paying attention. he flipped 360 degrees in the air and lost conciousness, but the only serious complication he had was blood in the brain.

in order for being shot to be like being hit by the truck, it would have to be the case where if you shoot the truck the gun passes enough energy to accelerate the truck to 35-40 MPH. Also, firing the gun would tear your arm off.
The muzzle energy, as quoted by Wikipedia is 2,010J, althought this will be less when it impacts it's target. It's muzzle velocity is 710 m/s, and its mass, 7.97 g.
Just checking, the Kinetic energy the bullet has is measured in Joules(J)
J = 1/2 mass x velocity2
= 1/2 (7.97x10-3) (710)2
= 2008 J
--------------------------------------------------------------------------
Now, for the truck. Lets say it's a standard 'medium' truck - around 10,000 kg for simplicity.
For the same energy as the bullet:
J = 1/2 (mass) (velovity)2
2008 = 1/2 (10,000) (velocity)2
2008 = 5000 (velocity)2
Velocity = root*[(2008)/(5000)]
V = 0.63 m/s
------------------------------------------------------------------
For the same force as an AK-47 round, a 10,000kg truck would have to be moving at 2.28km per hour! For the US lads, that's a pace of about 1.42miles per hour!
That being said, the bullet will exert it's force over an area many thousandths the area that the truck will, so the pressure or stress will be drastically less.
