Hmm. How does the elasticity model provide the additional constraint needed to give an unique solution?

- waqf 13y agoIt provides a way to apportion the impulse between the two simultaneous collisions. It behaves as a differential equation because the instantaneous force in each collision depends (via the elasticity model) on the instantaneous velocities of the balls, which in turn depend on how much momentum has already been transferred.
