Thor's hammer flies up into space in a second. Let's get the distance and the timeframe first.
Timeframe is 0.96s.
R = (h/2) + c^2/(8h) = (14/2) + 585^2/(8 X 14) = 3062.58036 X 2 = 6125.16072
Diameter of the Earth is 12756.2km.
object degree size = 2*atan(Object_Size/(Panel_Height/tan(70/2))) = 2*atan(6125.16072/(249/tan(70/2))) = 2.97041737 rad = 170.19237869377204 degrees
Enter that through the angscaler and we get a distance of 547.22km from the Earth.
T = 547.22km/0.96s = 570020.833/340.29 = Mach 1675.1031
Btw I didn't do the calc but I think the feat is this one.
Actually, our angsizing formula is object size * panel height in pixels/[object height in pixels*2*tan(70deg/2)].
So 12756.2*249/(6125.16072*2*tan(70/2)) = 370.2937658830490517 km
370293.7658830490517/0.96 = 385 722.6727948427621875 m/s, around Mach 1133.51
