Contest to win "A First Look at ASP.NET v2.0"

I'm feeling rather Canadian today, so the first person to correctly answer the following physics question gets my copy of A First Look at ASP.NET v.2.0.

On a frictionless 2D plane (like a pool table), a ball (B1) with an elasticity of E1 is traveling V1 units/second in the direction of A1 degrees. Another ball (B2) is also in this vacuum, with it's own elasticity (E2), velocity (V2), and direction (A2). If B1 is at (x1,y1) and B2 is at (x2,y2), and their paths will cause them to collide, where will they be after T seconds?

And if no one gets that question by today (which I swore I had in a Physics 101 class) ...

(x+5)^2  = 4x^2 -12x + 9
