Gravity of AT-5 (non-scientific bullshit)
This is probably going to end up being total bullshit, but I'll bring you along for the ride.
The scene where the sub/Simon are in free fall isn't as helpful as I had hoped it would be; Simon's fall is only on screen for about a third of a second, and there aren't a lot of good potential references for distance. Fuck it, I'm doing the math anyway. If I get 9.81 m/s² I'm deleting this blog.
Time
Had to pull this clip up in a video editor and skim through frame by frame to get the exact times. There's a total of 15 frames between when the sub impacts the surface and Simon hits the deck. At 24 fps, that means Simon is falling for approximately 0.625 seconds. His fall is only on screen for 8 frames/0.333 seconds.
Distance
This is trickier. The only thing in frame that I can use as a measuring tool is Simon himself. So fuck it, Simon's a ruler now.
Measured out 64 units and compared it to Mark's height (178 cm), so one unit is about 2.78 cm. Used the distance from Simon's shoulder to the top of his belt as a reference since that's what's on screen during his fall, which ends up being 16 units or 44.48 cm.
And now we move over to the first frame of Simon's fall:
Scaled up my shitty ruler and used frames from later in his fall to gauge where the center of his chest would impact the deck to get the distance. All in all we witness Simon fall 28 units, or 77.84 cm.
Calculating...
So I've got part of the distance that he falls, the time it takes him to cover said part of the distance, the total time it takes Simon to fall, and his initial velocity (0 m/s). Fuck. There's probably a formula for this but it's been too long since I took physics.
I can only get his average velocity during the period of time that he's onscreen, which is 2.34 m/s. The thing about gravity is that it's just a constant acceleration towards the ground; Simon's been in the air for 0.292 seconds already at the start of the shot, so his velocity isn't going to be zero. His velocity when he hits the deck isn't going to be 2.34 m/s either, it'll be slightly faster than that because again, average velocity. If I just say fuck it and use 2.34 m/s as his final velocity, I can plug that into a speed difference equation using the total fall time of 0.625 seconds and get 3.74 m/s² as his acceleration, but as soon as I plug that result into a distance via constant acceleration equation, I get 0.73 meters, which is less than the distance we witnessed him cover, aka it is wrong.
So basically, all I can say for certain is that Simon was definitely going faster than 2.34 m/s when he hit the deck, and that the gravitational acceleration is faster than 3.74 m/s².
I'll sleep on it and revisit it tomorrow. I'm definitely missing something.
