    Can a Police Officer Accurately Estimate Speed and Catch Up Within Seconds?

    I assumed this was a forum about physics (I am smart enough to read the website name). So I asked a question that I am having trouble conceptualizing which can be explained using a few simple formulas. If you have any input regarding the question, I would like to hear it, but if all you can do...

    Can a Police Officer Accurately Estimate Speed and Catch Up Within Seconds?

    What is the "1/2" that you have in your formula? And how do you go from 10 mph/s to feet traveled w/o converting it? Using A = (delta)V / T to find the acceleration of the police car I get: A = (51.33 fps - 0 fps) / 3.6 sec (time I interpolated it takes to go from 0 - 35) A= 12.83 fps^2...

    Can a Police Officer Accurately Estimate Speed and Catch Up Within Seconds?

    Right, but if what they SAY can be disproved by scientific fact, then their word becomes worth less (or even worthless). :smile:

    Can a Police Officer Accurately Estimate Speed and Catch Up Within Seconds?

    Sort of. What I am trying to show is that there would not have been enough time for him to catch up to me AND pace me for a couple of seconds by the time he decided to pull me...um, I mean my friend, over.. Since I made my first post I have done some more research and found a report from the...

    Can a Police Officer Accurately Estimate Speed and Catch Up Within Seconds?

    I hope that I construct this problem correctly. I am trying to...um, help a friend fight a speeding ticket. Thanks in advance for any help. The posted speed limit was 25 MPH. The officer was stopped at an intersection as I passed by him on the perpendicular and "estimated" that Iwas traveling...
