Calculation[]
Diameter of the planet - 12,742,000 meters and 439 pixels
Distance the rubble was blasted - 935 pixels
935 / 439 = 2.12984x
2.12984 * 12,742,000 = 27,138,421.28 meters
As the explosion was omnidirectional, I need to use the radius.
27,138,421.28 / 2 = 13,569,210.64 meters
Video runs in 25 fps
The initial explosion reached the sides of the screen in around 9 frames.
9 / 30 = 0.23
13,569,210.64 / 0.3 = 45230702.1333 m/s
Mass of the Earth - 5.972e+24 kg
KE = m * 0.5 * v^2
m = Mass
v = Velocity
5.972e+24 * 0.5 * 45230702.1333 ^2 = 6.1088078e+39 J = High 5-A
