For this purpose, isn't it force, not mass, that matters?
F = mv^2, so the velocity of bullet is a very large factor, especially when the terminal ballistics allow for most or all of the energy to be dumped into the target.
And the history of cartridges, the ability to "reload", make your own custom load, and the ability to stand off to let air resistance bleed off velocity, means you'd likely be able to apply the exact amount of energy you'd want.
- chronial 12y agoNo, impulse is what matters here, and that is mv. And force is ma. You must be thinking of energy.
- hga 12y agoYeah, I'm thinking of energy, but in this case I'm assuming the terminal ballistics will dump all the bullet's energy into the block that's hit (that it won't penetrate all the way through the block). Impulse is force over a period of time; in this case, doesn't it equals the same thing?
