Trying to figure out how far a car would travel in .004 second at 130mph. I somehow came up with 9.15 inches. Just wondering if that is correct or if it's not even close.

Last year I took the stripe by .0001@190mph, best we could figure it was about 5/16"......

Speed X 5280 divided by 3600 = distance per second
Therefore 130 mph X 5280 divided by 3600 = 190.66666 ft. per second 19.666 ft. per .10 second 1.9 ft. per .01 seconds .19666 ft. per .001
Another (faster but not as exact) formula used is speed X 1.47 therefore 130 X 1.47 = 191.1000

Minor quibble but if you took the stripe, your MPH is irrelevant. The trailing car's MPH is what matters.

Only changes it .01". Makes it a little closer to your 5/16", which is pretty much the right fraction to use. Some good work!

Thanks, but my Wife is a teacher, I'll have to credit her with that one...…
She did say it was a little over 5/16"
Just call me stripe hog!

Make it easier
17.6 x MPH x MOV in seconds
Also the MPH that should be used is the car that crosses the finish line second, which is not necessarily your MPH!

I think it is 1.467 x mov X second cars mph!

Same thing, just one is in feet and the other in inches!

TOP 38 has it 100% correct....below is the long version of where the 17.6 comes from
*5280 makes miles per hour feet per hour /60 makes feet per hour feet per minute /60 makes feet per minute feet per second *12 makes feet per second inches per second MOV is what part of a second you were behind
slightly inacurate in that the trap speed is assumed to be the speed during the MOVThis message has been edited. Last edited by: fast5982,
