0-60 distance traveled
I don't really have a safe/legal way of trying a 0-60 time, much less seeing how much distance it takes me, so I wondering if anybody knew how far they traveled, and what their time was, before reaching 60mph?
|
It's going to vary, but it's pretty damn close to 330ft. I know this because used to do many runs with a GTech, and the 330ft time was usually very close the 0-60 mph time in my stock RX8.
Random RX8 question... funny I knew the answer. |
Hmm, I calculated 264ft based off a 6 second 0-60 time, do you know how much time you it took for the 330ft run?
Thanks :) |

Thanks :) How are you calculating it? What the hell are you using this for? :lol2: |
Simple. Gather data on your velocity over time in a 0-60 run using a DAQ and your favorite data acquisition software (I prefer LabView), plug your data into excel, use a time step of ~0.05 seconds, plot it, fit a line to your data, take the derivative of your line, plug in your final time step, and voila! Total distance traveled. Oh and don't forget to convert all your velocities from miles per hour to feet per second.

^ man that sounds simple.
i've done the 330' in 6 flat, stock. so where does that put me yax? 5.7? 5.8? |

It was necessary to prove my point in court that there's no way I was paced at 60mph, I won the case, tickets dismissed, thanks guys :)

paint gun.. :)
beers :beer: |

I was "paced" at 60mph within a distance of 1,000feet after the cop took a 3sec time to react and begin moving.
I proved that if that had been the case (i.e. me going 60) I would have reached the stop light (at the 1,000ft mark) and already have slowed down significantly by the time the cruiser reached 60mph. I had several papers showing my math and explanation for everything, cop didn't have a comeback to anything I said so judge ruled in my favor, no court fees, all 3 tickets removed from my record (careless driving, 60mph pacing, missing registration). |
nice job dude, huge props. way to show that asshat.

You know, I once prepared the same thing. I got radared in fog once, and got a f'ing monsterous ticket because I was hauling ass. I know, I know, stupid, yadda yadda. It was stupid, and I was young. Anyways, I started doing the math on the dopler shift radar readings and how the water in the fog would affect propagation, and all this shit with micowave blah blah blah... it was back when I was in college taking some physics courses and I minored in math... I went to go fight the ticket with this paper, and sure enough... cop didn't show up, and I got off. Would have been damn interesting to present it. |
bwahah, i would have loved to see that be presented.
better he didnt show though. saves you time. |
Lol thanks :p:
Here's the short version of what I presented, I can't find the longer version I had written, but it's roughly the same stuff, just significant less detail and the longer version I explored all the different things which would have needed to happen in order for the cop to even manage 1 sec of pacing at 60mph. Mind you, any of this is without counting the fact I had a guy going 30mph in front of me. Enjoy http://www.tech-burrow.com/example/Dadeland.doc |
lolol, owned. :)

You're a bad ass. Much respect. If I helped any, makes me proud to be a part of it.

The speed of light and sound changes (not sure if radar uses light or sound) when the air is full of water which leads to miscalibration of the radar. Nice, I wouldn't have thought of it. :icon_tup: |
(not sure if radar uses light or sound) And guns are calibrated for the weather conditions...and to make it worse, water droplets ought to make it slower to get the signal back to the gun, which would show a slower speed than actual; in effect, you're getting a break from the moisture conditions, and the ticket is already lower than what you were actually going... Take that defense in court, and you're gonna' lose if the officer knows anything about his radar gun (they do). |

Umm... Neither...

If you were moving away from the radar and the wave was slower going through the medium it would appear that you were moving faster - red shift, blue shift. |

Nice job ENZO!!!!! I bet it was the same cop I had.... I still paid :banghead:
This was in Miami actually :p: |
