Firstly they are way too slow to be true "Meteors"...
...Most true meteors are much faster than these pieces of junk, and flash across the skys in milliseconds
It may be true that those normal quick meteor streaks we see zip through the sky ARE going fast (as you indicate),somewhere around 40,000 mph). But
they are tiny -- maybe like the size of a grain of sand or rice -- and burn up almost immediately when striking the atmosphere (and the streak we see
is the ionized gas around
HOWEVER, the medium-sized ones can last long enough to be slowed down considerably as they pass through the atmosphere.
The medium sized ones (let say the size of a basketball or even a small car) will hit the atmosphere at 40,000 mph, but are large enough to continue
to be slowed down as the burn up. the time it takes to burn up/break up can last a long time, which is why one of these events can be visible over
large areas and several U.S. states...
...BUT they eventually slow down quite a bit. They quickly slow down from 40,000 mph to 10,0000, to even 5000 mph and slower
as they burn
up/break up after slamming through the thick atmosphere -- which occurs pretty high up, about 60 miles, so even 10,000 mph looks relatively slow.
And by the time they get all the way through the atmosphere (if they get through) they have slowed down considerably, slow enough that they no longer
They would eventually be slowed by the atmosphere to terminal velocity
speeds, which for a remaining piece the size of a tennis ball could be
as slow as 150 to 200 mph before striking the ground.
They also seem too big, and give a green glow, which indicate copper.....a very human type metal, for electrical components etc.
Most meteors have high concentrations of metals. Magnets will stick to some.
