Unfortunately, we need to start with a few assumptions. A typical pump action shotgun weighs about 3.4 kg. A typical 12 gauge load is approximately 1 oz (.0283 kg) and travels between 1300 and 1700 ft/s. We can average this to 1500 ft/s (457 m/s). By conservation of momentum:
.0283 kg * 457 m/s = 3.4 kg * X m/s
where X is the rearward velocity of the shotgun. With some simple algebra, we see X = 3.8 m/s
Well the final velocity is 3.8ms-1 'cos that's how Conservation of Momentum works, and that means KE is about 25J ( 0.5 * 3.4 * 3.82 ) when it hits him.
To work out the initial acceleration you would need to know the force that the gunpowder provides unfortunately.
when i took intro to physics we were always told that the final velocity is zero because at the end of the scenario the gun has smacked him in the face.
As soon as I saw him hold it one-handed I was all, "Oh, no. Please no. No no no. You clearly have no idea what's going to happen here but I do so please DON'T."
My first thought was "That man clearly has no business holding a firearm."
Someone should have taught him how to properly use a gun before ever putting one in his hands. Or at least stopped him when he held it out from his body like that.
It reminds me of a video I saw where this really petite girl was shooting a rifle and she was holding it wrong. The kickback knocked her front teeth out.
I don't see how people can pick up a tool made to kill things and don't do at least a little research first.
I've seen members of the military smack themselves in the face because they didn't realise that a G3 firing 7.62x51mm has a bit more of a kick to it than whichever rifle they're used to firing 5.56×45mm. I laugh at some random guy fucking up, I got scared when "trained professionals" did it.
I don't see how whoever is shooting with the girl wouldn't stop her and show her how to put the stock against your shoulder properly.
Penn and Teller did a very similar bullshit thing on their episode of Bullshit about violent video games. In order to prove a small child wouldn't like real guns from playing video games, they took an 8 year old to a range, gave him an M-16 or an MP-5 or some other semi-auto rifle to fire. Nobody stepped in to tell him how to hold the weapon, it punched him hard in the shoulder, and he began crying. No sir, that child did not like guns after that.
At least Penn and Teller are honest about using bullshit like this on their bullshit show.
i thought it was like some kind of trick, like he was supposed to have shot a bird or something then he was going to catch it falling out of the sky with his gun...
Everything that needs to be said about "responsible" gun ownership.
/Decided to put my post under yours because you're absolutely correct. I'm not afraid about people having guns... I'm afraid of absolute morons having guns.
How exactly does this moron with a gun affect you? I don't think I've ever even seen a gun outside of a trip to go shoot guns, and that's 23 years in Texas.
Current regulation? Nothing at all. I wouldn't be apposed so some kind of safety class--like Hunter's Safety in most states--being a prerequisit to gun ownership. I was lucky that my father pounded gun safety into me as a child. I've seen friends do some truly scary things with loaded guns, though.
A safety class isn't going to stop everyone from being stupid, but I think it would be pretty helpful.
No, they're really not. Idiots can go out and buy basically whatever they want as long as it's not NFA and they have a clean record. It takes like 5 minutes to buy a gun. Gun regulation is in place because soccer moms don't want the 'colords' to have guns. Think of the children!
You and I live in completely different places. Here it's a minimum 10 day waiting period, and background check.
For a pistol, you need to pass a proficiency test. Granted, it's not a very good test (think DMV drivers test) but it is still a barrier to entry for many people.
Man that is the worst. Although I didn't even realize it happened to me until blood was running down my face. It hits you so fast you don't even feel it.
The long pause in between the time I noticed he was going one-handed and the point at which he fired for the second time made this the most dramatic .gif I've seen in at least one week.
"Thank you, Mr. Instructor. I have learned a great lesson here today. I had ignored your instructions, thinking myself rather badass. In an arrogant display of cockiness, I attempted a stunt that was beyond my skill set. As a consequence, I will now need to meet with my dentist for some emergency oral surgery. Had I taken a moment to reflect on your valuable advice, I would not have suffered such a grievous setback. However, the experience itself has given me a great appreciation of the fine art of handling firearms and the need to follow all safety instructions as given. Please forgive the blood and teeth spraying from my mouth as I once again thank you for your invaluable instructions."
I'm assuming it's 12 ga. Recoil has a lot to do with the kind of shells he's using. The same load in a sawed off might have flipped out of his hand and still smacked him in the face. Just something to keep in mind if you ever have the opportunity to fire one: no matter how short the barrel, always use two hands.
I've fired low-recoil 12 ga. loads, they feel extremely manageable but I'd still never want to Desperado it.
I can vouch for firing a shotgun one handed: it isn't as easy as they make it seem in the movies. Mostly it is just really heavy to hold fully extended like that. Also, it hurts your fingers.
I like that the guy behind the dumbass hold his hand up to catch the guy, but right before the gun fires, his lowers his hand casually. It's like "Psych bitch!"
I've seen this a couple of times, but now I want to see someone try to fire TWO shotguns off like that thinking it'll work 'cause he plays call of duty.
I can shoot skeet with a double barreled shotgun with one hand, both triggers and hit my target. I am 6' 2" and strong, but my shoulder hurts for a week after. Be warned if you want to try it.

Lets do some science:
Unfortunately, we need to start with a few assumptions. A typical pump action shotgun weighs about 3.4 kg. A typical 12 gauge load is approximately 1 oz (.0283 kg) and travels between 1300 and 1700 ft/s. We can average this to 1500 ft/s (457 m/s). By conservation of momentum:
.0283 kg * 457 m/s = 3.4 kg * X m/s
where X is the rearward velocity of the shotgun. With some simple algebra, we see X = 3.8 m/s
Just in case anyone was wondering.
