The front end of an automobile has been designed so that upon impact it progressively crumples by as much as .70m. Suppose that the automobile crashes into a solid brick wall at 80 km/h. During the collision the passengner compartment decelerates over a distance of 0.70m. Assume that the deceleration is constant. What is the magnitude of the deceleration? If the passenger is held by a safety harness, is he likely to survive? (Hint: Compare the deceleration with the accerleration listed of a parachutist in Table 2.2.)
