Collisions in 2D

  1. Oct 26, 2004 #1
    I'm designing a program that simulates collisions in 2 dimensions, among other things. The collisions are between 2 circles, the collisions themselves are perfectly elastic. The mass of the two circles are known, and their X and Y velocity components are known. They also have specific radii. I can easily detect collisions amongst 2 circles, but I cannot solve for the final Vx or Vy vectors of the two spheres.

    Any help would be greatly appreciated.
    Thanks

    As long as you are not including friction and spin all you have to do is exchange the component of momentum along a line joining their centers when they make contact.
