Title: velocity of fall
Post by: choc on February 02, 2008, 05:04:10 AM

hi there.
i'm going to calculate the fall velocity of shadow world.

therefor i need some informations.

1. is the density of air the same as on earth? (1.247 for 10?C/50?F)

2. what's about the gravitional acceleration? shadow world has a bigger mass, equatorial radius and another rotation duration? on earth g is about 9.8. which factor differs shadow worlds gravity to earth?

Ok. Lets see.
Kullthea has 28.5 hours a day. Density same as Earth. 8600 miles diameter. Gravity acceleration 9.80665.
Air is the same as on Earth with an increased density of 0.32% (up to 2000ft altitude at 10?C/50?F)

Human A has a weight of 165lbs
Human B has a weight of 232lbs
Human C has a weight of 199lbs
All have a std height of  ~5'10'' (different reference area of humans a & B changed by relation to human C)

Horizontal means face-down position, vertikal means standing or take a header.

Distances are in feet.

My Spacemaster Card for Ceril VII ( Also known as Kulthea by the natives )

Beside the quarantine 'shoot on sight and ask question latter' :
Circumference 39000Km
Mean Orbit 150600Km
Day : 28.5 Std Hours
Year : 1.01 Std Year
Gravity 1G
Hydrosphere 71%
Atmosphere : 21% O2 75% N2 3% CO2

The rest is not really relevant...

Dunno, but this may help. . .it's RM, but the logic may be close:
