There is almost no possibility of a meteor having that speed. The
maximum possible velocity a body in orbit around the Sun can encounter
the Earth at is 72 km/s. Anything faster than that would exceed the
solar escape velocity, implying either some sort of slingshot orbit or a
body originating outside the Solar System. Only a few meteors have been
observed with velocities above 72 km/s, and those only a bit more, and
perhaps of questionable measurement. More are in radar data (small
particles), but it has been called into question if these actually have
the velocities being measured.
Suffice to say, last night's meteor showed the characteristics of a low
to medium speed parent body- something between 11 km/s and say 40 km/s.
What is the source of the data you are using for your calculations?

Hello Listers
I found some info on the fall and here is some stats...
vel 667.2 km/s beg 135.8 km end 40.8 km
Now could a meteorite come from the Vel speed? I mean thats really fast
667.2km, or that could be a mistake, which I think it is? With the
meteor ending at 40km there is a possibility there could be some stones
on the ground. And after looking at the video I could see the meteor for
around 4 seconds and at the end the meteor got brighter.
more stats below...
