When an object collides with another object in an elastic collision, the first object exerts a force on the second object (and vice versa); how do you calculate the force that the object experiences? (and I am just thinking in terms of super basic point-like particles).
All I have been able to find on this has to do with calculating the resultant velocities of the collision, not the resultant forces. The next closest thing that I've come across has to do with impulses (http://en.wikipedia.org/wiki/Impulse_(physics)), but I'm new to all of this so I am not sure how to apply it (would an elastic collision of two point-like particles have an infinitesimal duration?).
Getting the force just seems like it would be pretty simple, so I must be missing something. I'm a beginner so any help would be great! Thanks!
