Makes sense. I hear his gamertag is 360noscopePaddock

See kids? Math will be useful later on in life.

Handwriting is completely digital. Could have been converted with the scanning software, but that does not look like pen on paper.

Also, fotoforensics appears to show it was superimposed. http://fotoforensics.com/analysis.php?id=3a366b5d398ccd6b4e02a637c6a7c8b64f63eee7.488300

I'm a novice myslef....but from what I understand, when you hover over the photo, anything that comes up as white, has been retouched.

Everything should be similar in color (black) but when you have sharp edges like that in white, then it's usually a separate layer in the document, or has been manipulated in one way or another.

It looks like someone wrote out the info on white paper, then cut the white layer of the paper away in photoshop, feathered it a bit and pasted the dark text onto a digital scan of the brown.. If you zoom in on the txt you can see the left over bright white pixels here or there in the writing. It's also why I suspect the lower straight line looks kind of like a pen running out of ink, being they had to hit feather a few times clear out the white back ground.

I'm pretty sure it's fake, but that's still just a guess. It's also possible that due to how the picture was taken etc that's why it looks that way. Yet go take and write out a bunch of notes right now and take a picture of them, none of them will look like that one does. Being the txt is clearly too digital.

It's also very possible all of that was done deliberately to mask how the info was leaked out. Yet if we were taking bets, I'm going with fake.

Jack Reacher anyone? Maybe he was assassinating a specific person, and killed 50 more to cover it up. Trajectory was to make sure he didn't miss that first kill.

Bump stock math.

Any "Math" people here on Reddit in general, that can explain it's meaning, even if it is authentic or not. Curious. This is like Kanji to me. Thanks.

I never rose to the level of math where there are triangles involved. Letters are where I left off.

The triangle is called delta. It means "the change in" so change in kinetic energy is the first term and change in potential energy is the second term.

I'm a junior in Aerospace Engineering right now. I see this shit all the time so I didn't stop to think that other people might not have learned it.

Im on my phone so won't be able to do the formatting but the V1i gets mixed up and written at Vi1 or Vii sometimes. This is the velocity of the bullet. Vf is the final (hence the f) velocity of the block and bullet together. (Imma keep 3diting this cause I'm on my phone and have to keep backing out to look at the photo)

I can't see this being anything more than a simple collision problem. Stuff like penetration would require a lot more math such as the things you listed. I think this is a fake photo that someone made to mess with people.

That is the mass of the block kg denoting kilograms- the metric unit of mass roughly equal to 2.2 pounds

It's kind of like that. My guess is it is a physics problem where the question gives a initial speed of bullet, the block and bullet mass as well as saying something like " right after collision the block-bullet system falls .8m. Find the speed at this point".

It says "block" which has a mass of .222 which is then hit by a bullet. The equations are solving for the Vf which is the final speed of the block and bullet together. This is like a highschool physics problem
