Link me the study from NASA, then. You probably should have just linked the relevant thing in the OP, rather than linking sources contradictory to your point.
Again, your own sources disagree with you on this. Meteoroids have a baseline speed of 11 km/s to enter our atmosphere, thus becoming meteors. I insist on the baseline speed because using the maximum speed is stupid. The average speed of a meteoroid is not 42 km/s, everything you have cited disproves this.
I don't care why you're arguing semantics, it's a dumb point.
You are making things up, though. Like objectively you're inventing words in your sources that do not exist. You, for some reason, have read the same bit as me (the bit that refers to the maximum speed of meteoroids as 42 km/s) and are saying that's the average. Your sole arguing point on this is arguing that because I used the term meteors, clearly the things have different speeds, totally ignoring the fact that the page this tidbit comes from is titled "Meteoroids". Pull it together, man. They aren't decelerating in the atmosphere, even 11 km/s assumes they have been sped up by gravitational pull accelerating them. It's agitating to repeat yourself, so please, read my words and those of your sources.
