Ok interesting, thanks. I got interested in this because in the movie, the android calls out their distance twice - "1800 meters", (waits 1.3 seconds), "1600 meters." Which means that according to the movie, they're going exactly 154 m/s (344 mph), and decelerate to 0 m/s in 16 seconds with...

Hmm you're right - Wikipedia says the simple equation only works for gas at low speeds. Although maybe I can get away with not having to go further into it - The big question I'm trying to answer is: I'm assuming an object traveling Mach 0.5 towards the spacecraft , suddenly entering the...

Oh wow I'm really that dumb. Thanks.

So in a spacecraft with regular air at 1 atm pressure, a hole gets punched in it (depressurizing it). I'm looking for the Exit Velocity of the air at t=0. Using Units: Internal Pressure: Pi = 1 atm = 101300 [kg / m*s2] Air Density: \rho = 1.2 [kg / m3] And Equation: Pi = 0.5 * \rho * (Ve2)...
