Gray Fox Deflects Bullets
Original calc by AguilaR101 all credit goes to them.
Context: https://www.youtube.com/watch?v=ki1IvQgFyME&t=342s
Very basic reaction feat, the blade is is 76 cm in length
Distance to blade
- 129px = 76 cm
- 37px = 21.79844961238 cm
In the time it takes for the bullet to cross that distance Gray Fox has twisted his blade 180°, therefore
Speed
- (2pi*76)/2 = 238.76104167282 cm for the distance moved
- Blade swing/bullet travel distance = 10.9531203328x
- FAMAS(F1) muzzle velocity =930m/s
- 930*10.9531203328 = 10186.401909504 m/s, Mach 29.93, High Hypersonic
Raiden Dodges A Railgun
Original calc by AguilaR101 all credit goes to them.
Pretty clear-cut, Raiden manages to swing his arms and move forward a bit before the projectile hits the crate.
For this angsizing seems like it could work.
Distance Railgun Round Travelled
- Fortune's distance to camera
- Fortune's height (From average US female height) = 1.618 /7.5
- Head = 0.21573333333
- 2atan(tan(70/2)*(45/720))=0.0592095361=3.3924565254659
- distance= 3.6425
- Raiden's distance to camera
- Raiden's Height (According to metal gear wiki) = 1.778 /7.5
- Head = 0.23706666667
- 2atan(tan(70/2)*(403/720))=0.518473844 rad = 29.706363049198
- distance = 0.44695 meters
- Railgun length
- https://en.wikipedia.org/wiki/Beretta_M9
- 49px= 21.7 cm
- 163px = 72.185714285691 cm or 0.72185714285691
- Subtract the last two values from the first one to get total distance
- Total Distance =3.6425 - (0.44695+0.72185714285691) = 2.47369285714 meters
Distance Raiden Moved
http://www.watchframebyframe.com/watch/yt/7MZ0LEL9t-o Set it to 60 fps
He starts moving from frame 4018, and by frame 4052 (when the bullet hits the crate) his arms have made almost a full circle.
- Arm Size
- 749px = 1.778 meters
- 296px = 0.70265420562 meters
- Half it since they're bent when he moves them = 0.35132710281
- Arm movement
- Judging by the video, he moves his arms roughly 7/8ths of a circumference or 315°.
- Distance: 2pi*0.35132710281=(2.207453290389764/8)*7 = 1.9315216290910435 meters.
Result
We only need to find a ratio of how much Raiden moved compared to the bullet, so: 1.9315216290910435/2.47369285714 = 0.78082516328, multiply by 100 km/s to get final result
Raiden Dodges Railgun Bullet = 78.082516328 km/s or Mach 229.458744976344, Massively Hypersonic
Old Snake Dodges A Railgun
Original calc by AguilaR101 all credit goes to them.
In this thread it was concluded that the speed of railguns in the verse can be scaled to Metal Gear REX's which can launch nuclear warheads at speeds above 100 km/s. Given that the portable railguns are minituarized versions of the same technology according to the MGS4 database and shoot much smaller projectiles than a nuclear warhead/missile It isn't a stretch to say they should have the same level of speed.
With that in mind, this old calc by Xcano can be revised with new values, credits to him for getting the hard math out of the way.
Since the only thing that changes here is the speed of the projectile itself, which was assumed to be
- Railgun Speed (Low) - 2000 m/s
- Railgun Speed (High) - 3500 m/s
We only need to find how much of a difference there is between 100,000 m/s and 2,000 m/s and multiply the number by the final results of the aforementioned calculation.
- Solid Snake Dodges Railgun (Low) - 210.15 m/s, Subsonic+
100,000 / 2000 = 50, multiply by 210.15 to get 10507.5 m/s
New Result
Old Snake dodges Railgun = 10507.5 m/s or Mach 30.88 Massively Hypersonic
