Thread: Tell me how to solve this

I've spent hours trying to figure this out. I'm building a particle engine for my thesis and I am having a hard time with this part of it.

I have two particles colliding and I need to know their resulting trajectories.

I know:

Mass of both particles
Velocities of both particles (both angle, magnitude and in vectors)
I know the angle between them

Attached is a diagram.

The distance between the two and the radii of them need to be irrelevant.

Is this collision perfectly elastic/inelastic?

Don't forget that you can use conservation of momentum to help you solve it.

I hope that helps.

It's perfectly elastic; ie there is no friction from the particles bouncing off of each other. I'm trying to conserve momentum.

Weird, the picture works fine for me. Here's an embedded one:

I just get a red x, can you upload it on imageshack or something? Or maybe just write out the variables.

I mentioned all the variables

Here is it on imageshack

Can't see that eiher, and I meant numbers .

I would help, but your picture is broken.
