Rockwell's AP[]
Another KE calc for Ark, this time for Rockwell .
One of Rockwells attacks is just a simple tentacle attack where he hits the player with said tentacles.
So first, we need the mass of one tentacle...
Scaling to the player, we see in the below images that the tentacles are around 16.6718m wide, and 109.229m tall.
Using the volume of a cone we find the volume to be 7948.3m3
And since Rockwell is a mutated human we can assume he has a similar density to us with 985kg/m3
This means that the final mass is 7,829,075.5kg
7 Thousand Tonnes!
These tentacles move in a curve, using circumference we can find an approximation of this path.
So to find this we assume that the tentacle is the radius of our imaginary sphere, using the images we have already shown we get a circumference of 686.307m.
since the tentacle doesn't move in a full circle, we can assume that it goes around 1/4 of the way around considering it is pretty much perpendicular to the ground. So we simply divide by 4.
686.307 / 4 = 171.57675m
So that's how far the tentacles move in a small amount of time, but how much time does it take?
As shown in this video, it takes 11 frames for the tentacle to reach the ground, the video was recorded at 30fps so this is 0.366 seconds
171.57675 / 0.366 = 468.788934426m/s
The tentacles surpass the speed of sound!!
Given all of our values we get a final KE of:
0.5 * 7829075.5 * 468.788934426^2 = 860270814156J, or 205.609659215105 Tons of tnt!
That's 8-A, Multi-City Block level!
Also Supersonic attack speed for Rockwell. This likely doesn't scale though.
So if this gets accepted this could be a pretty big upgrade for the bosses and other relevant creatures that scale to Rockwell.
Method 2 (According to corrections):[]
Apparently I used the wrong method and a slight wrong timeframe, time to correct.
According to 100 Megaton Tsar Bomba a different formula should be used, rotational KE:
So the timeframe wasn't 11 frames, it was more around 5
As previously found:
mass: 7,829,075.5kg
lenght: 109.229m
time: 0.167s
circle: 686.307m
angular velocity: 2*3.14/0.667 = 9.424776 s
moment of inertia: 1/3*7,829,075.5*109.229^2 = 3.113617e+10 kg*m^2
rotational energy: 1/2*3.113617e+10*9.424776^2 = 1.382857e+12 Joules, or 330.5107552581262 tonnes of TNT, still 8-A, Multi-City Block level
