RE: Accelerometers
I can see from this and your other posts that you have a very limited understanding of physics. It looks like you have a better understanding of what is commonly known as “Roadrunner Physics”.
The distance flown on 2.5 mile course is typically in the range of 2.7 to 3.0 miles, plus the time it takes to accelerate from a standing start. The 2.5 mile figure is a point to point distance for 10 laps.
At a speed of 170 mph, you have a velocity of 250 ft/sec
The formula for acceleration in the turn is V^2/R
V^2 is 62500 ft^2/sec^2
Divide by 50 (ft) and you have 1250 ft/sec^2
To convert to g, divide that by 32.1 ft/sec^2
The result is 38.9 g
