So, if I can obliterate the volume a weaker substance, but only marginally damage another substance, meaning it is stronger but still capable of causing damage, how would I find out how much energy it would take to destroy the equivalent volume of the first substance for the second substance in...
But if you destroy more volume with granite using the energy required, and less volume of an unknown, stronger substance, doesn't that mean the volume isn't the concern?
What if it were possible though? Would it be as simple as creating a ratio between the volumes, which would also be the energy difference?
I don't need a specific answer, just a general sense of direction.
Hypothetical question:
Let's say there's a granite cube with a volume of 60 cubic centimeters. A cannon ball is shot at it, reducing it to rubble, and the kinetic energy of the ball was 10,000 joules.
We use the same ball with the same kinetic energy output on a stronger unknown substance with...
Yeah with that last suggestion it really helped, I was able to make sense of the formulas linked above, the only thing I need to check is if my bullet measurements were correct.
Yeah, I meant just weather conditions, not gravity and stuff.
But with one of the calculators I used to find speed over time, I needed the ballistic coefficient, muzzle velocity, and diameter and weight of the bullet, so I don't know how that'll help.
I found a few Pejsa things, but this is...
Hi, I engage in physics as a hobby, and I'm not extremely familiar with things reaching into calculus levels of math. That said, how would I find the velocity of a bullet at a given time or distance, taking wind/humidity/etc. out of the equation?
I know the muzzle velocity only applies to the...
