Introduction[]
In Sword Art Online, the 100th floor boss attacks Kirito and his party with giant vines, destroying a large portion of the battleground. I'll be calculating the power of this attack and Kirito and his party's durability.
Calculation[]
First, we need to find the length of one of the spheres in AINCRAD's hair. I'm going to use this image where we can see Kirito compared to AINCRAD.
Scan 1
Kirito = 171 cm
Sphere Length = 162.12 cm
Second, with the sphere we can find the length and width of the destroyed ground.
Scan 2
Sphere Length = 162.12 cm
Attack Length = 115.45 m
Attack Width = 152.85 m
Third, we need to find the height of the destroyed ground.
Scan 3
Kirito = 171 cm
Giant Vine = 124.24 cm
Scan 4
Giant Vine = 124.24 cm
Attack Depth = 1.32 m
Finally, we put these values on this Rectangular Tank Volume Calculator to get the volume.
Volume = 23293.4229 m^3 or 23293422900 cm^3
Fragmentation of rock is 8 j/cc.
Energy = 23293422900 x 8 = 186347383200 Joules, or 44.54 Tons
Final Tally[]
AINCRAD's Giant Vines = 44.54 Tons of TNT (City Block level)
Only one vine hit the group, so we need to divide the result by six.
Kirito and his party's durability = 44.54/6 = 7.42 Tons of TNT (Large Building level+)
