If I understood the original question correctly, the issue isn't the speed
of the meteorites at the time they fell (which was presumably just the well
understood terminal velocity for objects of their mass, size, and shape),
but whether the entry velocity was higher than usual for a body that
produces meteorites. It is generally accepted that meteorites are most
likely to be produced when the parent is on a shallow entry angle, and
traveling at the lower end of the possible speed range.

Dear Geoff and Met List,
  After thinking more about my reply to your question
I wish to apologize if I appeared rude. This was not
my intent.
  Perhaps your question can be answered indirectly IF
soil conditions and any penetrations (craters) were
observed. Most likely too late. Another possible
means would to find a rock of a similar structure and
hardness and IF there were any broken PF mets
duplicate how much force it would take to break the
stone.
  These are the only ways that I can think of to
perhaps estimate the velocity of fall for PF.
  I hope this helps in your question. Sincerely, Dirk
Ross...Tokyo

  This would make a good research paper for someone
with the time to do the research.
