Would someone who is taking some physics classes tell us what the approximate mass of a bullet would need to be to move a 165 lb person? I know there are a lot of variables from friction to muscular resistance (like stepping backwards) but that's why you're taking physics classes! Someone with more expertise should give a reasonable approximation of the velocity of a "typical" bullet.

On the program they tested the 7.62 that the AK-47 uses and it did succeed at knocking down a stationary 180lb target when shot in the head. It barerly fell down but it did knock it down. Now I don't know how well it would work if the person is running towards you and weighs more than 180lb, so take it as is. The M-16 on the other hand was unable to do this though, but this is, of course, because it uses a smaller 5.56 bullet.

Not even a shotgun shot will blow a human backwards (unless the subject jumps in fright). Even with all the force in a bullet, it simply isn't enough to blow an object as big as a human forcibly backwards. Depends on the rating. Level III is rated to protect against a 7.x62x51 NATO, and a level IV is rated to protect against a .338 Lapua Magnum (IIRC) |

In the case of a bullet proof vest, all of the bullet's energy would be dissipated into the target, therefore it's more likely to fall over. |

But the question is, did the bullet penetrate the target, or was the target solid enough for the bullet to dissipate all of its energy into it? If the bullet passed through then only a small amount of its energy would have been transfered into the target. |
