Introduction[]
In Wonder Woman (2017), Diana raises her arms fast enough to block lightning that was fired by Ares. I'll be calculating her speed.
Calculation[]
Diana is played by Gal Gadot in this movie, who is 5'10", which is about 1.78 meters.
Diana's Height = 1.78 meters = 110 px
1.78 / 110 = 0.016182 meters per px
Distance between Diana and Ares = 502 px = 8.12 meters
We don't see the distance between the lightning and Diana as the lightning travels, but we do know based on the video that Diana walked a bit further and she blocked some time after it was fired, so I'll assume the lightning traveled at least half this distance by the time Diana blocked it.
Distance between Diana and Lightning = 8.12 / 2 = 4.06 meters
Also shown in the video is how she blocked it. She raised her arm up and then moved her forearm in front of her. After rewatching this several times and even physically replicating the movement myself to be sure, I've broken it down into two movements: a 90 degree movement of her arm, and another 90 degree movement but of only her forearm.
Via some additional pixel scaling that will not be shared here, I got an arm length of 0.76 meters and a forearm length of 0.42 meters.
Arm Movement = (2 * pi * 0.76) / 4 = 1.19 meters
Forearm Movement = (2 * pi * 0.42) / 4 = 0.66 meters
Total Movement = 1.19 + 0.66 = 1.85 meters
Speed of Lightning = 440000 m/s
Diana's Speed = (1.85 * 440000) / 4.06 = 200492.61 m/s
Final Result[]
Diana Blocks Lightning = 200492.61 m/s; Mach 584.53 (Massively Hypersonic)
Getting the arm movement was so annoying.
