This game involves both slow motion and hard to work with camera angles to determine said slow motion. However, none of this is really a problem, as we have confirmation as to what factor the game's time is dilated by.
When standing still, time slows to a crawl, a mere 1/200th its original speed. This means that apparent speeds, like the katana swing above, are actually 200x faster than they appear. So how fast is that swing?
To determine that, I'll have to assume that the Player has a normal height and normal proportions.
The average American has a height of 1.76 m, and the regular proportions for an adult human being look like this. Since the katana is being swung about the elbow, this means the radius of its swing arc would be 0.25x the Player's height, or 0.44 m. We know the swing is about 90 degrees in total, and that it takes an apparent 0.05 s in-game. So the only thing left is to find the apparent speed of the swing, and then the actual speed through the 200x multiplier.
C = (2)(pi)(r)
- pi = 3.14
- r = 0.44 m
(2)(3.14)(0.44) = 2.76
The arc is 90 degrees, so it'd be 0.25x this for a swing arc of 0.69 m.
v = d/t
- d = 0.69 m
- t = 0.05 s
0.69/0.05 = 13.8 m/s
And now we multiply this by 200x and...
(13.8)(200) = 2760 m/s
Result
- The Player Slices a Bullet - Mach 8.11
