| Jul 25, 2015 at 23:28 | comment | added | Mark | @njzk2, yes. The terminal velocity of a crowbar (500-600 m/s, the velocity it "wants" to fall at) is small enough in relation to orbital velocity (7000 m/s) that the dominant force for most of reentry is momentum transfer between the projectile and the atmosphere. | |

retain a reasonable velocity at impact did you just completly ignored gravity?
