CHAPTER 1 THE REAR END COLLISION
In this chapter we will describe in detail the impact of a rear end collision with one meganewton force on the occupants of a unibody four door economy car with specificity regarding all four passengers, one in the driver's seat front, one in the passenger seat front rear driver's side and the rear passenger side. The rear end collision with a force of one meganewton is an extremely high and hard impact. The effects of such a collision on the occupants of a unibody or economy car would be severe. Here's a detailed breakdown for each occupant.
Driver’s Side Front Driver’s Seat:
Whiplash . The driver is likely to experience severe whiplash due to the sudden jolt from behind. The cervical spine would be subjected to a rapid back and forth motion, which could result in tearing of ligaments, muscles, and tendons in the neck. It's really important here to understand that there is a thing that happens to our ligaments in these types of hyperflexion and hyperextension injuries, and it's called ligament laxity. And what that means is that the ligament is stretched out of its normal shape, and it never ever ever goes back to its regular shape. When this happens to us in a whiplash type injury, the ligament can no longer hold our head up like it should. As a result of that our muscles take over and try to hold the head up where the ligaments would do it before because that is taxing to our muscles. That's why we get aching necks and pain. That is constant because our muscles are working overtime, trying to take over the job of the now stretched ligaments.
