I was thinking about meteorioids and how upon their entry into the atmosphere the large amount of disintegration they experience so i wanted to try running through a calculation of something similar to see if i could i understand it better. I'm going to outline a general thought process I've come up with then ask a specific case.
Ignoring gravity or the existance of a floor for now because of the complications that would cause.
Lets say we have a [insert size and mass/density here] [insert shape name here] of [insert material here] [falls apart/does not fall apart] and we fire it at [insert velocity here].
How [long or far] will it travel before the object fully disintegrates?
How [much mass/volume] is lost before the object stops disintegrating.
Lets say we have a 1 meter radius sphere of iron (density 7.874 g·cm−3) in 1 atm air. We assume it does not fall apart or explode in it's transit. We fire it at 100 km/s, how much mass does the object lose in its transit.
