Re: Again :-] : Re: Again: origin of bird flight
At an average velocity of 5 mph & 7 mph for fractions of a second, it don't
make much difference.<
Hmm...speaking of mph, a few fellow list members and I have had a little
problem with the V=.25g^.5*SL^1.67*H^-1.17 (speed formula).
With a height of 3.9624 meters, a stride length of 9.144, I get a speed of
12.59 m/s, which, if I do the the math right, comes out as 45.32mph.
However, other list members get much slower speeds (11.52 mph), using the
same formula. I was wondering if anyone more familiar with calculating speed
knows what we(most likely I) are/am doing wrong.
