Calc GaoGaiGar - King J-Der vs ZX-26

King J-Der destroys a Primeval (ZX-26) merged with one of Jupiters Moons. In the GaoGaiGar Denki Data Collection, this is confirmed to be Ananke.

31 PRIMEVAL SPECIES
ZX-26 Kidney Prototype
A progenitor tsed with Ananke, Jupiter's 12 satellite, and faced the final battle on Jupiter. It engaged the combined fleet of J-Ark and GGG in Jupiter's satelite orbit, and was destroyed by King J-Der.

Ananke has a mean radius of 14km (or a diameter of 28km) and an estimated mass of 29,973,368,661,943,900kg. The Moon is a bit odd shaped, so we'll have a low end and a high end with different radii.
(Low end)

669 pixels = 28km
1pixel = 28km/669 = 0.0418535127km
0.0418535127km X 480 = 20.0896861km

(High end)
293 pixels = 14km
1 pixel = 14km/293 = 0.04778157km
0.04778157km X 480 = 22.9351536km
The timeframe is 5 seconds and 22 frames (with a framerate of 30 frames per second).
T = 1s/30
= 33.3333333ms X 22
= 0.733333333s + 5s
= 5.73333333s
Now let's get our timeframe...
(Low end)
T = 20.0896861km/5.73333333s
= 3504.01502m/s
(High end)
T = 22.9351536km/5.73333333s
= 4000.31749m/s

We can finally get our kinetic energy!
(Low end)
KE = (0.5)mv^2
= (0.5) X 29,973,368,661,943,900 X 3504.01502^2
= 1.84008328e23 joules
= 43.979045889101335831 teratons
(High end)
KE = (0.5)mv^2
= (0.5) X 29,973,368,661,943,900 X 4000.31749^2
= 2.39825016e23 joules
= 57.319554493307840914 teratons

Final Results
King J-Der destroys ZX-26 (low end) = 43.979 teratons
King J-Der destroys ZX-26 (high end) = 57.32 teratons
