A 100 car train is pulled by a 200T locomotive. Assume that the cars are all identical and weigh 100T each. The train accelerates from 0 – 10m/s in 200s, and we ignore friction and air resistance. Roughly sketch this train as a single object (you don't have to sketch all 100 cars). - What is the mass of the entire train (in Tonnes and kg)? - What is the train's acceleration in m/s^2? - What is the (tractive) Force supplied against the rails by the locomotive in N and kN to accelerate the train? - What is your day of birth (dd)? This is your car number counting back from the locomotive. - Draw the FBD for your single car on this train while it is accelerating, and briefly explain forces. - Find weight and normal force (magnitude and direction) for your car, add these to the FBD. - Calculate the forward coupler tension (magnitude and direction for the attachment point of your car to the forward part of the train pulled by the locomotive) for your car, add to the FBD, and explain.

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.

(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.
