I am trying to show that the Batman scene where the tractor trailer flips over the long way is completely unreasonable.

I would like to use, as a very simple model of the problem, Principle of Impulse and Momentum.

So please help me out. I have a truck traveling at some constant velocity. It drives straight into a "trip wire" tied across the road to two lamp posts. Now, assuming that the lamp posts and the wire and the truck do not fail and fall to pieces, I would like to find out how fast the truck would have needed to have been going in order to create a moment about the wire.

Could I have a little assistance in setting this problem up?

I know that the trucks momentum could be said to act at the Center of mass. Is the point on the truck where the wire strikes a "force" ? And how so I find its magnitude (dude)?

The scene is http://www.youtube.com/watch?v=81LeooTiKI0" for those who have not seen it. It's at 0:45 seconds
