Pretty basic stuff. Tentomon is stuck distracting Kimeramon while T.K. beats the shit out of Ken.
Ken is kind of crouched, but Devidramon is very crouched, so whatever.
Ken's around 1.524m.
(1.525/91)711.4=11.9m
(11.9/9.2)435.5=563.3m
Here we have to angsize for the base's distance. The frame size is 4/3.
2atan(tan(70/2)*(4/3))=86.067076523132
And the frame width is about 1067px.
2atan(325/(1067/tan(86.067076523132/2)))=31.748370787872
d=990.43m
Frame rate for this episode is 23 fps, and Kimeramon's attack reached the base from ~perspective in 15 frames. Therefore, the time-frame is 15/23rds of a second.
990.43/(15/23)=1518.66m/s
or about mach 4.5.
Almost scratching hypersonic. Tentomon was able to dodge this attack by moving about his body length before the attack could propagate ~the length of his body. Basically, I'm saying this applies to the Adventure Rookies.
