0-60mph metric
I use to know this, but it’s gone. 1.05 60’ long car. At what distance, is it going 60mph?

Maybe I am totally missing your question. My apologies.....

BG Isn’t that equation based on a constant acceleration? I know my G force trend on my data logger peaked at 3g on the leave and came down pretty fast.

So, that metric is often used in car reviews. A quick street car is 0-60mph in 3 sec or so. I was thinking a typical dragster with 1.05 60’ may be under 1 sec for 0 to 60 mph?
Of course the time slip does not show that.

Yes. That is the average velocity. Best would be to probably plot it out on excel and use a best fit exponential. Been a long time since calculus. That is simply how the mph is calculated at the end of the track 60' / interval time to finish line. I can remember the days when there was the 60' after to try and get a more accurate mph. Velocity isnt changing much the last 60' so it's pretty accurate. I'm sure there is someone smarter than me to help you out on this.

Perfect thanks
Just in case anyone else is interested, you need a 1.045 60’ to be doing 60mph at 60’
