Impact of a horseshoe hitting a metal stake

[Photon713]

I am trying to write a program in Action Script that describes the reaction of a horseshoe hitting a stake based on the design of the impact location, i.e., rounded, flat, etc., and the velocity of impact. The location of the center of mass is known. The impact location can vary depending on the angle of arrival. Assuming that if the horseshoe arrives perfectly square to the line of flight the horseshoe would bounce straight back. I'm interested in what happens if it arrives unsquare and hits a flat or rounded surface to the left or right of center. At his point I'm only interested in the initial reaction a few moments after arrival. Any formula or reference to such, would be appreciated. Thank You
