if you are in a car that is struck from behind, you can receive a serious neck injury called whiplash. using newton's laws of motion, explain what happens to cause the injury. how does a headrest reduce whiplash?

The Head is at rest, and which whole body experiences force from the back which leads to getting equal force in the neck causing whiplash, it follows the first Newton's laws of motion.Newton's first law of motion states that any object will stay at rest until and unless any external force is applied to it in order to move. And as the object is having some mass therefore force of inertia acts on the object simultaneously. When the car struck from behind, the body which was in contact with the car experienced force that compel it to move, however, the head was not in contact with the car resulting in it being in rest position. Therefore, for matching the accelerating force of what the body experiencing, the force transmitted through the neck from the body causes an injury called whiplash.A headrest is in contact with head which can exert the force needed to accelerate the head with the body and the neck won't have to apply the required force.To learn more about Newton's law, follow the below link:https://brainly.com/question/27573481#SPJ4
