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.
