How Long; How Far?
 

Bullet is 300g Deep Curl with a muzzle velocity of 1880 fps. The questions are: What is the time of flight? How far from rifle to jug?

Winner gets an autographed copy of SEMISANE' ramblings, first edition.

Note a portion of the jug, flying toward the camera, at the lower right just outside the water, with a reddish tint.

Is the mic at the jug? No way to judge it. By the time we hear the sound it hits the jug.

202 Yards

.3223 Seconds

How did you come up with that?

That was cool, but I have no idea.

Let's see if I'm close and then I'll share. I want that collection of Semi's ramblings.

That was 60 yards, .0748 seconds. There were 3,854,291 water droplets produced. :D

HINT: Camera records 30 frames per second. Pause the video, and count, using the arrow keys to move between frames.

It doesn't matter what time the primer pops. All that matters is when the bullet leaves the muzzle. I don't think you can tell that from your video. So you can't count frames to determine the time of flight. Tom.

In that first frame shown here, the bullet has not yet left the barrel, however in the very next frame after, a beginning puff of smoke is the giveaway, that the bullet is on the way.



The next frame reveals the smoke puff growing larger, but the bullet has not yet arrived at the jug.



In the following frame the bullet has just arrived at the jug, and the smoke from the rifle continues to spread.



Several frame later the jug is long gone; the smoke plume grows, and water drops fly across the front of the camera.



In order to learn the time it takes for the bullet to get from the rifle to jug; one just counts frames between the second picture shown above and the first frame one comes to, that shows the bullet impacting.

the way i do math that is a heck of a poke.
14-15 frames = approx. .5 seconds
1880 fps = 940 ft.

The bullet starts to slow down the instant it leaves the muzzle; your calculation doesn't take this into account.

Frame count is real close; could be improved.
