Calc Drakengard 2 Feat - Cannonball Speed and Power

Calculations
The Feat

The watchframebyframe

Not a bad speed feat for the seemingly archaic tech *shrugs*

Legna = 307 pixels

Tower Width = 716 pixels

Tower Width/Legna = 2.332

Legna = 25.4 meters (comparable in size to Angelus)

Tower Width = 59.233 meters

Cool

Now, organization for this is kind of annoying, but bear with me as I explain shit

The travel distance I'm working with begins at this point here. Here, you'll notice the tower looks like a fucking afterimage as it travels. I want you to focus on the right most of the pair of afterimages as that is the genuine tower. Upon reaching this time point here the cannonball has traveled the distance I'll be using to measure its speed as it is an image in which an entire afterimage of the tower has been past by the cannonball thus clearing the entire width of the tower's distance.

That being said, I first need to find the distance the cannonball traveled during the slowed down portion of the cinematic.

After all, there's a clear disparity between the portion where the cannonball is fired from the cannon and when we take the cannonball's perspective while it travels towards Legna

So, from here to here I'll derive a distance the cannonball has traveled and use the time between here and here to get an additional distance the cannonball traveled offscreen before it reached the first frame of the cannonball POV here. Having derived that I'll subtract that distance from the green line measured distance of the first image behind the spoiler tag.

So, math and all that fun shit now

Image 1

Tower Width = 101 pixels

Wall = 10 pixels

Distance = 924 pixels

Distance/Tower Width = 9.149

Wall/Tower Width = 0.099

Distance = 541.923 meters

Wall = 5.864 meters

Images 2-4

Wall (Image 2) = 140 pixels

Cannonball Diameter (Image 2) = 96 pixels

Distance 1 (Image 3) = 80 pixels

Distance 2 (Image 4) = 530 pixels

Distance 2 - Distance = Total Distance = 450 pixel

Cannonball Diameter/Wall = 0.686

Total Distance/Wall = 3.214

Cannonball Diameter = 4.023 meters

Kind of large, but they look pretty damn huge in game anyway given the respective Dragons being shot at are also pretty damn big *shrugs*

Sphere Diameter = (4/3)PIr^3

Cannonball Volume = 34.074 m^3

Iron Density = 7,900 kg/m^3

Cannonball Mass = 269,184.6 kilograms

Total Distance = 18.847 meters

Time Frame = 0.1 seconds (here to here)

Speed of Slowed Down Portion of Cinematic = 188.47 m/s

Time Post Distance = 0.87 seconds (here to here)

Distance Further Traveled = 163.969 meters

Which brings us back to Image 1's distance

Total Distance = 541.923 - 163.969 = 377.954 meters

Which was traveled over a time frame of

Time Frame = 0.12 seconds (here to here)

Cannonball Speed = 3,149.617 m/s or mach 9.256

These are things both in game and in cinematics that Angelus and Legna dance around

KE = 0.5mv^2

m = Cannonball Mass

v = Cannonball Speed

Cannonball Yield = 1,335,167,358,733 joules or 319.113 tons

Because why not derive it when 2nd Form Legna was struck by it and more or less fine *shrugs*

Final Tally

Cannonball Speed = 3,149.617 m/s

Cannonball Yield = 319.113 tons

I do high school physics for stupid shit because I find it fun for some ridiculous reason.

I'm neither a physicist or engineer. I study psychology.

Before taking me at my word, think for yourself and don't just appeal to the shit I'm posting without evaluating it yourself. That should go without saying. I'm not an expert, do not treat me like one.
