Supersonic speed on spy×family (?)

Nightfall speed.

Context: Yoru with a small fraction of his strength throws a tennis ball faster than sound and Nightfall is able to react.



We use the racket as a reference in the pixel scalling, the size of a racket goes from 68 to 77 centimeters, we use 73, the result gives us that the distance between the tennis ball and Nightfall is 123 cm, we are going to approximate it to 125 It is seen that the ball is crossing the sound barrier so we use a speed of mach 1.1 or 377 m/s, since it will travel 125 cm we calculate.

1.25m ÷ 377m/s = 0.00332s

This is the time frame in which the movement is made, the movement seems to be the image that I put:





It's a basic tennis move where you move your hand back and then make a semi-circle to hit it, come on Let's say her arm is 65cm which should be average for a Belgian woman (SpyxFamily seems to take place in Belgium) then to find out the semicircle and adding the initial movement we say:

65+Pi(65) = 269.2

So our distance traveled is 2,692m, we divide it with the time we have and it comes out:

2.692m ÷ 0.00332s = 810.84 m/s = Mach 2.364, supersonic speed.
 
1. This should be in VSBW not in Joke Battles
2. This should be in calc discussion not General discussion
