9. A 100 kg-motorcycle at rest starts to move from point A with a constant acceleration. At that time there is a 500 kg-car in front of the motorcycle which is traveling in the same direction with a constant speed of 12.0 m/s. The distance between the front end of the motorcycle and the back end of the car is 180m at t = 0. What is the magnitude of net force acting on the motorcycle if the motorcycle reaches the back end of the car at 10.0 s.

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?
