I had graphed my best 1/4 mile time in excel and was able to fit a curve to it that was basically a perfect fit. I need help understanding how I can obtain my 0-60 time from it.
The formula is: y = -0.1481x^3 + 7.612x^2 + 11.966x - 0.7681
Where y = feet down the track, and x = seconds
I figure my speed is my slope, so I need to take the first derivative of this formula and find out where I hit 88 feet/second (that's 60 mph)?
I always hated calc...

humm...got to say pretty interesting. I'll give it a try.
Three Wheelin'
-3(0.1481x^2) + 2(7.612x) + 11.966 - 88 = 0
Graph that on your caculator and you will get the answer.Your time may be in negative.
hhmmmm..... interesting .....
