Good day all,(adsbygoogle = window.adsbygoogle || []).push({});

I've got a rather puzzeling question on hand that is part of my Dynamic project. I need to model the collision of two vehicles. Each vehicle is traveling head on to the other, and each one has a spring attached to its front. We can assume that the final velovity after collision is the came for both vehicles. I need to set up an ODE for the system and solve for position vs. time for each vahicle. I have tried this by combining the springs into one spring upon collision but this would not be corrct since the compression of the spring would not give a correct value since there are actually two different springs with fdifferent k's meaning different compressions. If anyone has any help, that would be great.

Regards,

Nenad
