However, just before that, I think it is 10 m/second squared 01-27-2012 04:38 PM mikieg isnt the terminal velocity of gravity 220mph? 01-20-2012 02:21 PM steveg353 Udderly incredible! Sorry, someone had to go there. It is FRIDAY and I am going sailing for the weekend!!! I will now include scanning the skies as a part of my situational awareness...lol 01-20-2012 09:05 AM bljones 01-20-2012 09:03 AM bljones "phobos-grunt" sounds like a natural childbirth method. 01-20-2012 08:57 AM Bene505 Quote: Originally Posted by steveg353 View Post I wonder what the terminal velocity of a cow would be from 30,000'. It would depend on if it were beef or dairy I suppose. 135 mph would be my guess, since people are about 120 mph and it's based on surface area to volume ratio IIRC (similar density). Air resistance goes up dramatically with only slight increases in speed, hence the smallish, 15 mph increase, even though the cow is much heavier. Hello, Mythbusters?

What does space debris smell like? It the moment after impact? Burning fiberglass, Dacron and diesel, mixed-in with holding tank contents. Then and there'd be a lot of steam everywhere. I guess that qualifies as stinky. Regards, Brad This thread has more than 10 replies. Click here to review the whole thread.
