Basically, I'm wondering how you can essentially determine the bearing of a signal source, if you know its signal strength. assuming you're in a vacuum, and you have a beacon transmitting a signal, and you know its signal strength. How could you find out the bearing (direction) it's at, if you...

And I suppose the equation gets much more complicated when you start to factor in things like air resistance, friction between the barrel and projectile, etc.? Anyways, thank you all for your answers. :)

So, according to that, in order to propel a 10kg object at 10m/s, through a horizontal 2m long barrel in a vacuum, you'd need 1250 Watts of power to propel it at that speed? And no, this isn't homework. Right, I forgot about that when writing the post. Say it's uses 400V (U), then I (Current)...

(Title is actually supposed to say: How do I calculate how much power/current etc. is required to propel an object forwards at a certain speed using electromagnetism? but it's too long for the title tab, apparently.) So, I'm wondering how you calculate the amount of power/current etc. is...
