me and my mates had 400m marked out on the road and from stoped to the other end i was going 165k 3 times in a row does any one no how quik that would be roughly also wats the verdict on the g-tecs
my car is after market s/c exhaust and little bits but i dont want to go to the calder park drags i will get laughed at probly.
Speed=Distance/Time, so transpose the equation, Time=Distance/Speed
But remember that is using constant values, as your speed will increase exponentially, therefore your final value may be wrong.
calder is overrated nowadays ... ya cant beat the 2am, out the back of dandenong or tulla or filo drive or whatever drags... THATS the fun stuff
but how do you get time?
Speed = 102mph
Distance = 400m yea?
so that means Time = 102mph / 400m ? .255 !!! whooooooosh quik run dude!!
somethings wrong with that.. maths isnt my srong point
oh .. i get it
time = 400m FIRST divide by 102mph SECOND
dude thats still a 3.9 second run!
yea ok i suk at this
the verdict on the g techs is they are around $500 at auto barn and $65 on ebay.
i got one off ebay and they are prety accurate.
when getting one off ebay ask for a metric one if you can.
KW not HP
KM/H not MPH
Try to make sure the quarter is not running up or down hill with a g tech because it runs off g forces (gravity) and must be kept as level as possible
Check out My SV8 One Tonner
You can get a lot farther with a kind word and a gun than a kind word alone
do you guys think it would be mid to low 15s
Yeah, I found that out with the G-Tech. Really need to make sure road is level.
oi dude... stop n ave a think 4 a minute ur trying 2 work out spedd, time etc
... u cant use 400m and then 102mph... u gota use metres n metres or miles n miles.. so there fors use 250miles not 400 metres
ok kids if you want to work it out the real way use speed in metres per second (m/s-1) and distance in metres. your answer will come out in seconds. and if i could remember where i put last yrs physics books i'd get out the equations and do it.
You cant work it out like that.
Time = distance / velocity
ONLY holds if you were doing a constant speed and NOT accelerating at any time. So, if you were doing 165 km/h when going over the start line the formula would hold and it would take you 8.7 seconds or so to get to the 400m mark.
If you use the uniform acceleration formula, you also get the wrong answer. It really can only be calculated by the dynamic acceleration (like when you use a g-tech).
