Need some quick help...ballistics/penetration question

[davidjinks]

Is there a formula that would show me potential penetration of an item when fired from a barrel?

If I know velocity, weight and distance could I calculate potential penetration depth?

Potential to penetrate what? A rock, automobile body or a live chicken???

What item from what barrel? A spitball blown through a soda straw qualifies as an item fired from a barrel.

You need to be a lot more specific.

Is this for a physics class and/or video game? If YES, check out:

If you want to know about a jacketed lead bullet going into an oak tree or a deer, not so much. Too many variables.

[davidjinks]

Not a physics class.

Those links are excellent for what I need.

Thank you!

Unfortunately I can’t be more specific.

THIS is how you answer a question with INFO..not a bunch of useless hyberbole. I too appreciate your response.

Truly,

I have a much bigger appreciation for Isaac Newton now. Even more than before.

Although, this question is a little weird/different. But, hey, I am a paranoid person to begin with.

When extinction-level-event rampaging meteorites are outlawed - only outlaws will have extinction-level-event rampaging meteorites.

:D

I don't think the same equations work accurately for typical bullets at typical speeds impacting typical targets (animal and/or vegetable), but I'm not an engineer or physicist. They be reasonably accurate for a typical bullet into a sand pile or similar.

[davidjinks]

The first 2 links are perfect.

Unfortunately the last link will not work for me. It is based on objects entering the earths atmoshpere and is used as a prediction tool for “large” impacts.

When I converted my numbers the result was so minuscule that the screen just stated...”your object is so small that it burned up in the earths atmosphere.

The first link is a definite homerun for me/my uses/needs.

This came about because of a work project I’m on. This would be considered atypical.

Why do I think I need to be smoking pot to understand this thread? It's only been 50 years since I smoked pot. It made me feel pretty stupid then and I cannot imagine it making me feel any smarter today. What am I missing?

[davidjinks]

You shouldn’t feel any way about it. I just needed a scientific formula to calculate penetration. I suck at google/internet stuff but I do know there is a good bit of knowledge here. That’s why I asked for help.
