the answer to this can only be two numbers The human head can be considered as a 3.3- kg
cranium protecting a 1.5- kg
brain, with a small amount of cerebrospinal fluid that allows the brain to move a little bit inside the cranium. Suppose a cranium at rest is subjected to a force of 3000 N
for 7.0 ms
in the forward direction.Part C
The cranium now hits an external object and suddenly comes to rest, but the brain continues to move forward. If the front of the brain interacts with the front of the cranium over a period of 18 ms
before coming to rest, what average force is exerted on the brain by the cranium? include untis!!!
