Brett: "Foul, my friend!" I'm still with you, but the Lake Placid
track is not instrumented to do what you describe and those values
can't be derived from the givens. Besides, if you are taking us down
that road, you didn't go nearly far enough! <grin>
Okay, I propose we take this off-line and into Professor West's
virtual classroom. We can push around the problem a bit there and if
things get out of hand, then we'll simply have to move it into Lisa
G's classroom to get it solved. If you are interested in following
this further, send me a DIRECT e-mail saying you want in on the
discussion and I'll start a new thread. This way we'll keep the
ADK-Luge discussion board about the sport and not Newtonian physics
which is where we might be headed. --Jim D.
