I need to confirm that a physics/maths formula will provide me with the correct data to combat a speeding problem in my road that the local police will do nothing about......

I need to prove that vehicles can accelerate and achieve high speeds within certain distances and then that proof can be used to contradict a senior officers report.

so, I found a maths formula D = Vo x T + 1/2 A x T xT and think that a car will achieve within 5 seconds a distance of 125ft, is that right?

I am using 10 for A ( 10ft/sec/sec ) and half that for motor cycles?

Is there a better way of establishing how far a vehicle travels in a specific time? for example..... a Subaru Impreza WRX STi will do 0-60mph in 5.4 secs so how far has it travelled, or a Kawasaki ZX6R j2 does 0-60 in 2.9 secs so how far?

If I can establish a formula to work this out then I can have multiple points at which numerous cars reach 60 mph on our road and it will destroy his argument!!

any help gratefully received, I would absoultely love to shove some physics/maths data up his snotty nose, 'cos you just can't argue it.

thanks in anticipation
