If you take the formula for acceleration in EVE:
-ln(0.25)*Mass_kg*Agility/1000000
and plug in the missile values (1500kg and 1000 agility) you find that it takes ~7 seconds to accelerate fully.
Then using the formula for acceleration:
V at time t = Maximum Velocity * (1 - e^(-time * 10^6 / Agility * Mass)
you can work it all out and find that the maximum range of your golem is: 38.01km.

There are still a few of them left?! 
Don't see much of these 1337 posts anymore!
*bows to the nbernes*
Btw, wth happened to you name?
It's backwards! 
Thank you. 
About the name, well it's a long story. Let's just say that Cat isn't all that good at science, and as detailed in this thread was playing around with some clone vats...

however the actual range is between 37-38km...
Seems fairly in line with the predictions I've made. And yes, transversal velocity also comes into it, but 38.01km is about the top limit of range for Javelin Torps on a Golem with no implants and rigs.

I like this T2 Cat.
Thank you!
In more forum-whoring apprenticeship I have found the formula for many things. They might come in useful one day...

don't forget to stock up on some devices, as they do things! should be interesting to see what you cook up with some useful formulas and things that do things!
and out of all the torp range questions I've never seen anything beyond oh it takes a bit to accelerate, chop off a few km, I need to bm this one. Kudos!
What needs to happen now is for someone with a lot of time and more than just a Maths A-level to come and integrate the speed formula so we can have a proper missile range calculation.
And no, I can't do it...

Right, I decided that I couldn't leave it at that, so here is a formula for working out missile range taking acceleration into account:
Quote:
t/3*v*e^(-t*250000/m/a)-11/12*t*v+t/6*v*e^(-t*500000/m/a)+t/12*v*e^(-t*1000000/m/a)+t/3*v*e^(-750000*t/m/a)
where:
t=flight time
v= Maximum velocity
e= exponential constant
m= Mass of missile
a= Agility of missile
It's only an approximation, but it gives pretty good answers.
Major respect for anyone who uses it though.

My formula will be inaccurate, because it's an approximation of integration with Simpson's rule. I'm impressed that theres a neater formula for it all though.

I'm highly amused that a pair of flight speed rigs appear to be better than a pair of speed and flight time rigs.
If/when this formula ever gets put into EFT, the price of flight time rigs will plummet.
