If I read you correctly, the problem is statically determinant and 
shouldn't require software. The cable mass is so small with respect to a 
car that you can even do the dynamics. Where'd the 6 kip load come from? 
Would I be too far off if I guessed a 3000 lb vehicle and 2g 
deceleration? If I'm not too far off, you might want to verify 
this--lateral loading puts a helluva tension on a cable.
