Re: wheels come off - speed doubles?

[Larry Cartwright <exit60@CABLESPEED.COM>]

Ken, you must have missed a couple of essential messages in this
thread.  A "speed doubled" remark by a police officer appeared only for
a short time in an early version of the news report.  The report was
then changed to its present form.

Like many list threads, this one makes sense only if you have followed
all the steps in its unravelling.  The Phys-L archives at
<http://lists.nau.edu/archives/phys-l.html> should fill in the gaps for
you.

Best wishes,

Larry
