Hey, you're the expert!

I'm just trying to do some college Physics 101 (got yer' old green and yellow Halliday & Resnik book?)

GAG! My prof would be laughing if he saw me looking up those darn projectile equations!

Doing an analysis on the observation of the astronomers from Cal Tech. We can guess their position from the Cal Tech website: http://www.ovro.caltech.edu/

The Owens Valley Radio Observatory (OVRO) is the largest university-operated radio observatory in the world. The observatory is located near Bishop, California, approximately 250 miles north of Los Angeles on the east side of the Sierra Nevada. For reference, its coordinates are 37°14'02" latitude, 118°16'56" longitude at 1222 meters above sea level.

By use of following website one can convert deg/min/sec to decimal.

The Cal Tech observatory is at
37.23389
-117.71778

Now looking for testimony of astronomer... I seem to recall it in this thread.... hmmm...

Saw your comment XBob... Will plot on MapPoint the datapoints you guys have over NM

The first big problem is coming up with density vs. Altitude equation I can put in Excel. I entered values every 10,000ft and came up with a table that I plotted in Excel and did a trend line.

I'll use D=.0024e^(-.00004*Altitude) until I have I have time to make it a little better.

D is in slugs/ft^3 and altitude is in feet.
I'll use CD = one for now.

Drag=Area*CD*AirDensity*V^2

Area would be the average of the six sides.
