1. The consequences of a head-on collision of two automobiles can be studied by considering the
impact of the automobile on a barrier, as shown in figure below. Construct a mathematical model (i.e.,
draw the diagram) by considering the masses of the automobile body, engine, transmission, and
suspension and the elasticity of the bumpers, radiator, sheet metal body, driveline, and engine
mounts.
