2d Collision Physics

  1. Jul 17, 2008 #1
    I am trying to analyze the physics of a 2d collision among polygons. I supplied you with an image that illustrates my attempt:

    Now, object A moves with a velocity Vi while object B is still, as indicated on the image. According to my analysis, object A will transfer its velocity (momentum) through point P to object B which will receive the velocity with a vector perpendicular to the normal (blue line). This will further decompose into angular and transitional velocities which i have no problem doing.
    When I tried to simulate that with a program (when a point hits a figure, the collision looks realistic) however what I am confused about is the final velocity of object A after hitting object B, or to be more precise the direction of the final velocity....

    Does anyone have any idea? Any help will be greatly appreciated.
