Feat:[]
L kicks Light making both of them fly, I'm gonna calculate the KE
Weight:[]
Average Japanese weight = 60 kg
Since both of them fly I will use 120 kg
Speed:[]
The scene has a lot of slow motions and camera movement so to find the speed I'm gonna use the instance where L start to fly.
He was in a normal stance but he flipped due to Light flying away, L is 1,79 m, he did a 90° rotation so a movement of 2,81 m
Time frame = 13 frame (using this)
1 frame = 1/25 = 0,04
13 frames = 0,52 s
Speed = 2,81 / 0,52 = 5,4 m/s
Result:[]
KE = 0,5 x 120 x 5,4^2 = 1749,6 Joule (Street Level)
Small Update:[]
From this comment here.
Light's weight (and I assume at this point L's weight should be closer to Light's one) = 54 kg
Total weight = 108 kg
Result = 0,5 x 108 x 5,4^2 = 1574,64 Joule (Street Level)
