Final answer:
Increased time of impact from crumple zones in cars reduces injury to passengers by lowering the force experienced during a crash. Enhanced driver training helps ensure safe vehicle operation, and operational limits like those set by the FAA prevent fatigue-related accidents.
Step-by-step explanation:
Cars today are designed with parts that crumple or collapse during a crash to protect the passengers inside. The correct option that explains how this feature increases safety is option (a): It reduces injury to the passengers by increasing the time of impact. By increasing the time over which the crash takes place, the force experienced by the passengers is reduced, as stipulated by the impulse-momentum theorem. If a car experiences a longer impact time, the force on the passengers at any given moment during the crash is less severe, which can be easier for the human body to withstand.
Considering the CVSE intervention steps to improve safety, enhanced driver training programs are crucial because they prepare drivers to handle their vehicles safely and responsibly in a variety of conditions. Additionally, guidelines like those provided by the WHO surgical checklist and operational limits set by the FAA are preventative measures to combat fatigue and enhance focus during critical tasks, thereby reducing workplace and operational accidents.
