The bullet traveling slower would result in the smear being shorter, not longer… you said it should be 4.5 inches long at 3,000 ft/s, then said it would be 6 inches long at 2,000 ft/s.
Maff.
Well, that's what I said. I was mentally comparing it to the image that was taken. The problem, as I said at the outset, was that the camera speed and the bullet speed are not in synch, if the streak is taken to be the bullet
At 3,000 fps, and 1/8000th sec exposure, a streak would be 4.5 inches. At 2,000 fps, and 1/8000th sec exposure, a streak would be 3 inches.
According to this camera the 3000 fps assumption gives a 12-inch streak, so a 2000 fps assumption would correspond to an 8-inch streak.
Thanks for the catch. My apology and embarrassment. But it makes my point nonetheless.
