# VS Battles Wiki

We have moved to a new external forum hosted at https://vsbattles.com

We have a new automated signup system for our wiki members, with a procedure that must be exactly followed in order to register.

At InfiniteDay's request, I am doing my version of calculating Robo Fizzo's "reaction" to a sniper bullet at close range. The calculation of this moment is already there. But I disagree with him for some reason.

In fact, I disagree that there is a bullet reaction here. In the comments under the same blog, I wrote why. I ask you to review them before saying whether the calculation itself is correct or not. I do this calculation simply out of interest, what will I get in response.

Now, I agree that there is a reaction. I changed my mind.

## Let's start

Blitzos's height without horn is 1.48112280702 meters.

Blitzos's height without horn is 1.85079114943 meters.

InfiniteDay and I agree that Blitzo was aiming at the red one in the circle.

I am going to make several calculation options. I will use the distance based on the muzzle length of the sniper rifle (RED LINE) and not counting the muzzle length (BLUE LINE). The bullet starts its way at the beginning of the muzzle. But as I was told, the wiki doesn't take that into account. But I haven't seen anyone from calc members or admins write about this directly. Also, I am going to use several different Fizzo's diameters. The first option is taken from my previous calculation. And in the second, I'll try to find the diameter through Blitzo's height (PURPLE LINE). Because in this frame, the diameter is just slightly higher than Blitzo's height.

Distance traveled by a bullet, taking into account the muzzle:

1.85079114943 / 249.5 × 457.5 = 3.393735274 meters.

Distance traveled by a bullet excluding muzzle:

1.85079114943 / 249.5 × 253.6 = 1.88120495189 meters.

Possible diameter:

1.85079114943 / 249.5 × 283.9 = 2.10597037003 meters.

I assume that Fizzo managed to make exactly one circle, because he is spinning so fast that the eye cannot keep up. The effect is the same as with a helicopter propeller.

Movement = (2.10597037003 × 360 × π) / 180 = 13.2322020863 meters.

Diameter from the previous calculation:

Movement = (2.99490597617 × 360 × π) / 180 = 18.8175492259 meters

## Speed

Bullet speed is taken from here.

### Low-Low-Low-End

Snipe Speed = 790 m/s

Movement = 13.2322020863

Distance = 3.393735274

Speed = (13.2322020863 × 790) / 3.393735274

Speed = 3,080.21657678 m/s, or 9.05946051994 mach (Hypersonic)

### Low-Low-High-End

Snipe Speed = 910 m/s

Movement = 13.2322020863

Distance = 3.393735274

Speed = (13.2322020863 × 910) / 3.393735274

Speed = 3,548.09757578 m/s, or 10.4355811052 mach (Hypersonic+)

### Low-High-Low-End

Snipe Speed = 790 m/s

Movement = 18.8175492259

Distance = 3.393735274

Speed = (18.8175492259 × 790) / 3.393735274

Speed = 4,380.38405716 m/s, or 12.8834825211 mach (Hypersonic+)

### Low-High-High-End

Snipe Speed = 910 m/s

Movement = 18.8175492259

Distance = 3.393735274

Speed = (18.8175492259 × 910) / 3.393735274

Speed = 5,045.75885066 m/s, or 14.8404672078 mach (Hypersonic+)

### High-Low-Low-End

Snipe Speed = 790 m/s

Movement = 13.2322020863

Distance = 1.88120495189

Speed = (13.2322020863 × 790) / 1.88120495189

Speed = 5,556.77872189 m/s, or 16.3434668291 mach (Hypersonic+)

### High-Low-High-End

Snipe Speed = 910 m/s

Movement = 13.2322020863

Distance = 1.88120495189

Speed = (13.2322020863 × 910) / 1.88120495189

Speed = 6,400.84637585 m/s, or 18.8260187525 mach (Hypersonic+)

### High-High-Low-End

Snipe Speed = 790 m/s

Movement = 18.8175492259

Distance = 1.88120495189

Speed = (18.8175492259 × 790) / 1.88120495189

Speed = 7,902.30956682 m/s, or 23.2420869612 mach (Hypersonic+)

### High-High-High-End

Snipe Speed = 910 m/s

Movement = 18.8175492259

Distance = 1.88120495189

Speed = (18.8175492259 × 910) / 1.88120495189

Speed = 9,102.66038709 m/s, or 26.7725305503 mach (High Hypersonic)

There are somehow too many options...

## Result

• Low-Low-Low-End = 3080.2 m/s, or 9.05 mach (Hypersonic)
• Low-Low-High-End = 3548.09 m/s, or 10.4 mach (Hypersonic+)
• Low-High-Low-End = 4380.3 m/s, or 12.8 mach (Hypersonic+)
• Low-High-High-End = 5045.7 m/s, or 14.8 mach (Hypersonic+)
• High-Low-Low-End = 5556.7 m/s, or 16.3 mach (Hypersonic+)
• High-Low-High-End = 6400.8 m/s, or 18.8 mach (Hypersonic+)
• High-High-Low-End = 7902.3 m/s, or 23.2 mach (Hypersonic+)
• High-High-High-End = 9102.6 m/s, or 26.7 mach (High Hypersonic)

Definitely not three-digit mach numbers.

### Update

I changed the results due to the fact that Blitzo was higher than we thought. But the results have hardly changed. The difference was literally one billionth of a m / s. Sometimes the answer came out more than it was. Sometimes less. Well, but everything has become more true. At least something pleases.
