> velocity only applies to something in free fall, not to something with a high magnitude inertial vector relative to the Earth (like a meteorite) It could be conceivably coming at a speed high enough to still be supersonic when it hit the ground. However, were that the case, I doubt there would be still much of a house remaining. Or maybe a block for that matter, depending on how fast it was going. More likely, it just slowed down due to friction. This is even more likely for a small rock. > anything with thrust (like a supersonic plane or a bullet). Plane has thrust, but a bullet doesn't ;)
