Ok, so let's say I have a weapon that can fire a 2 centimeter diameter rod that is 25 centimeter long at a speed of 1/3 the speed of light, or 100,000,000 meter seconds with a weight of 5kg.
I estimate the energy at 2.5 e16 joules, or approximately 6 megatons.
Now, my question is complicated, I figure a large part of that energy will be heat as it starts to touch the atmosphere at the barrel's mouth as it exit the weapon.
How do I go about calculating how much energy would probably be wasted burning up in the atmosphere on the surface of the Earth if I shoot the weapon to the horizon, so say going through roughly 100km of dense atmosphere at normal sea level.
Next how far do you think such a rod would travel down to the center of the earth?
Next loud would this potentially be? from this site

I'd estimate between 275 decibel or so.
finally, the air molecule it hits as it exit the weapon, would the rod cause a shower of mainly x-ray? Or is it possible that it would create mainly gamma ray as it travels and interacts with matter?
thank you very much for your answers.
