Or at least I can calculate it...
That's not so easy ... remember, the effect of the air on velocity is
Vo*e^-(bt/m) where b is the balistic constant of the parachutist. That can
vary considerably with long-terme effects of diet, exercise, etc.
Assume a spherical parachutist, as in all good Physics problems? ;-)
Hmmm...I've just thought that I've been lurking on this list for some time,
and posted once or twice, but never really introduced myself. So, for the
purposes of brevity:
Hi all :) I'm a student who likes lots of old kit, but doesn't have the space
or the money to store and buy some really nice stuff. Most I manage to get
from skips or University department clearouts. I
don't seem to have anything
as interesting as you guys have at home, but for
those who care: Sharp
MZ-80K, Apple ][c, Acorn BBC B, Perkin-Elmer DataStation 3600, Microvax 3600,
MicroVAX 3800, Data General mv2700 (IIRC), a Sun 3/50, and assorted PCs, some
Amstrad Word Processors, and a couple of other Suns. I may have missed some
things out.
I'm here to learn as much as possible about any equipment, and maybe even
contribute something useful at some point :-)
