Final answer:
Car safety features like airbags and crumple zones increase the time of impact during collisions, reducing the force on passengers and hence the chances of injury. The correct answer to how crumple zones protect passengers is by increasing the time of impact. For the rabbit crossing question, while theoretically possible, safety also depends on other traffic and environmental factors.
Step-by-step explanation:
Using lights during the night can significantly reduce the chances of a collision because your vehicle is easier to see. Padded dashboards, airbags, and crumple zones in cars are designed to extend the time over which a collision occurs, resulting in a reduction of force experienced by the passengers. Specifically, cars have parts that can crumple or collapse in the event of an accident, which protects the passengers by increasing the time of impact, thereby reducing the force exerted on passengers during a collision. This is because the momentum change (a product of mass and velocity) is constant, but extending the time over which the collision takes place results in a decrease in force, as per the impulse-momentum theorem: impulse equals change in momentum which is force times time.
The correct answer to question 10 regarding how crumpling parts protect passengers is: a. It reduces injury to the passengers by increasing the time of impact.
In the scenario with the rabbit, if the car is traveling in the furthest lane from the rabbit, and assuming no other vehicles are present, the rabbit might be able to cross all 3 lanes safely. However, this is also contingent on traffic conditions, the rabbit's speed, and the responsiveness of other drivers on the road.
