A transport safety laboratory tests two different prototype vehicles of the same mass and length, Vehicle A and Vehicle B. Both vehicles are propelled at a speed of 16 m/s16\text{ m/s}16 m/s and crash into a solid concrete barrier. During the crash, the front end of Vehicle A crumples, allowing its passenger compartment to travel a further distance of approximately 0.8 m0.8\text{ m}0.8 m before coming to a complete stop. By contrast, Vehicle B has a rigid frame and its passenger compartment travels a distance of only 0.2 m0.2\text{ m}0.2 m after impact. Explain why Vehicle A is safer for passengers than Vehicle B. In your answer, estimate the deceleration of Vehicle A during the crash and compare it with the deceleration of Vehicle B.
