OK. I'm not real big on Physics, but I know that there are others in here that are a bit more physics oriented than I am.

Picture for a moment two cars stopped at a traffic light. Red car and blue car. Excuse the rough drawing below. It's just for illustration purposes only.



Enter into the picture gray car lets say traveling at 25 MPH. Gray car doesn't see that traffic is stopped, and slams into blue car, which in turn hits red car. Would there be a pronounced whiplash effect on red car over blue car?

A little history on this is my wife driving the red car, was hit waiting at a red light in the rear by the blue car because he was hit by the gray car. The gray car was deemed responsible for the accident and has to pay costs pertaining to the repairs and hospitalization of my wife for whiplash. (Not to mention the blue car who was really caught in between.) Am I making any sense?

Weeks went by and my wife went back to the doc because of continued and unrelenting pain, and they finally ordered an MRI of my wife's neck and they've found 3 herniated discs in my wife's neck. She's in a great deal of pain. Now the doctor has to make a determination of whether the accident caused this, or if it was something that happened earlier. Now we know that she wasn't having a problem before the accident. But proving it is a completely different story.

I'm theorizing that there would be an increased whiplash effect over the "slingshot" effect. But does my theory hold water? Of course any of your statements aren't really legally binding, but I'm trying to look at all the possibilities that are available to me.

** BTW.... I'm going to be posting at several forums trying to get the broadest range of answers. So you don't need to answer twice if you've seen it before. **

I doubt that there is any slingshot effect, but, apart from the friction, the blue car, brakes, still in gear, the effect on
the Red car, would be about the same, if the Blue car, wasn't present.
The kinetic energy, from the Grey car is transferred to the blue and red car, whithout much loss, depending whether brakes are used, by the
Blue car

It's a bit like playing a ball game like biljart, same priciple.

the kinetic energy would transfer from gray to blue but if the blue car was not applying brake presure almost all the energy would hit the red car. but some cars can absorb more of the energy than others so the red could be worse than all.
hope your good ladie recovers my friend

Well, I see an update is needed here. She ended up with 3 herniated discs in her neck area. She got treatment, but declined surgery.

She's doing OK, but still has problems with this accident. She did receive a very meager pain and suffering sum. All in all, the sum she got, was more or less what she lost when she couldn't work. I wasn't really happy, but what're going to do?
