1. How does the acceleration experienced by a fighter pilot compare to the potential acceleration experienced by passengers and vehicles in a crash? What acceleration does an occupant feel when decelerating to a stop from 40 m/s in a tenth of a second? How d oes this change if the time is doubled?
2. What is a "crumple zone"? What is their purpose, and why do they increase safety during a crash? Refer to specific physics concepts.
