The human head can be considered as a3.3-kg cranium protecting a 1.5-kg brain, with a small amount ofcerebrospinal fluid that allows the brain to move a little bit insidethe cranium. Suppose a cranium at rest is subjected to a force of2800 N for 6.5 ms in the forward direction. (a) What is the finalspeed of the cranium? (b) The back of the cranium then collideswith the back of the brain, which is still at rest, and the two movetogether. What is their final speed? (c) The cranium now hits anexternal object and suddenly comes to rest, but the brain continues to move forward. If the front of the brain interacts with thefront of the cranium over a period of 15 ms before coming to rest,what average force is exerted on the brain by the cranium?
