Apr 5, 2021 at 20:07 | comment | added | puppetsock | It's a ridiculous accuracy story, but let that pass. Do the following math. How much energy is required to slow a 1 ton projectile from 10 km/s to zero? And what temperature will copper be heated to if it absorbs that much heat? AND what acceleration is required to do this in, say, 100 meters? Does any part of this thing make it to the ground, or is it very small shrapnel even if it works as intended? | |
