Calc bububuki 2 (bubuki buranki)

oubu dashes at high speed causing a pretty decent explosion
timeframe is 0.58 seconds
now let's get the crossed distance

the skycrappers on the surrounds have around 18 stores
which means they are 74.515 meters (53 px)
the height oubu crossed is 220 px (309.307 m)
S=309.307/ 0.58
S=533.288 m/s
i already got his volume as 1624.81594 m^3
steel density is 7800 kg/m^3
Mass=1624.81594 x 7800
Mass=12673564.332 kg
KE=M x v^2 x 0.5
KE=12673564.332 x 533.288^2 x 0.5
KE=1.8021561e+12 joules

oubu dashes again and this time his fire propulsor does some flashy shit

the floor is 2 px (3.5px)
dash lenght is 444.775 px (778.356 m)
dash diameter 124.65 px (218.1375 m)
shaping it like a ellipsoid is 19392668.02027 m^3
density is 1.225 kg/m^3
mass=19392668.02027 x 1.225
mass=23756018.3248 kg
specific heat of air=1005 j/kg . k
temperature of blue flame averages at 2500 k
average is 20 degrees or 293 k
Q= m x c x T
Q= 23756018.3248 x 1005 x (2500-293)
Q=5.269168e+13 joules

oubu pickes entei and flies throught he sky till he establishes himself
timeframe is 4.07 seconds

oubu is 163.22 px (37.08 m)
house is 2px (5m)
panel height is
2*atan(163.22 /(461/tan((70)/2))) 19.046 deg
or about 110.52 meters
now the house is
2*atan(2/(461/tan((70)/2))) 0.23555354 deg
or about 1216.2 meters
distance covered is 1216.2-110.52= 1105.68 m
S=1105.68/ 4.07
S=271.665 m/s
mass is 2 times oubu mass
mass=12673564.332 x 2
M=25347128.664 kg
KE= m x v^2 x 0.5
KE=25347128.664 x 271.665^2 x 0.5
KE=935332775466 joules
