Do you understand ballistics?


#1

If you stand on a platform and hold a gun exactly 16.087’ above, and parallel to the ground, and the ground is flat and level as far as the eye can see. You now shoot a 150gr 6.5mm bullet with a muzzle velocity of 3000fps. How long will it take for that bullet to hit the ground?

  • half a second
  • One second
  • One and a half seconds
  • Two seconds

Where are the crayons? I need them for this math stuff.


#3

I don’t know ballistic math like that so I chose what made sense.


#4

hmmm…is this a # of feathers vs a # of bricks all over again? :thinking::thinking::thinking:


#5

I knew what variable I needed to find but did not remember exactly how to find it. I looked it up after I made my guess to see if I was correct. I was not. :sob:


#6

The exact reason why my dumbass bought a BDC scope!


#7

LOL. I’m getting the same results on Twitter.


#8

Gravity be gravity.


#9

You should see the people over thinking it on twitter. What’s the air density, what’s the BC of the bullet, on and on.


#10

gravity is 32ft per second squared…


#11

Sooooooo, did I get it right?


#12

Looking at the results, only 27% are right.


#13

Damn. Here I am thinking 9.8f/s^2, when it’s 9.8m/s^2.


#14

It seems somewhere in the dark recesses of my pea brain is the notion of -
A bullet dropped by the shooter equals the flight time of that same bullet to target.
Yes, No?


#15

True except for the “to target” part. Gravity affects the bullet as soon as it leaves the barrel. So a bullet dropped from the same height at the same time the other leaves the barrel will hit the ground at the same time.

The 32”/s squared is acceleration not velocity. So with an initial velocity of zero the bullet will drop roughly 16 feet in the first second.


#16

To be exact, the distance fallen is 16.087 feet, or, 16’ 1.044"


#17

LOL. Another assumption is we’re on earth right?


#18

Not to mention the trajectory if the shooter jumps into the air as the trigger is pulled.
Or if the shooter is running along the top of a speeding train.
At an angle of 12 degrees to the target.
Or…, now my brain is getting tired.
