Question

In a collision, which of the following occurs?

a) The occupant’s internal organs slam up against their skeletal structure.

b) The vehicle hits an object.

c) The occupant hits the interior parts of the vehicle.

d) All of the above.

Answer 1

In a collision, the vehicle hits an object, the occupant hits the interior parts of the vehicle, and the occupant's internal organs can slam against their skeletal structure. The correct answer is d) All of the above. Modern car safety features like dashboard padding and airbags help to reduce injuries by absorbing impact and extending the collision duration.

Step-by-step explanation:

In a collision, several events occur simultaneously and in quick succession, often resulting in substantial damage and injury. Specifically:

• The vehicle hits an object, which is the initial contact during a collision.
• The occupant hits the interior parts of the vehicle due to inertia, which continues to move them forward until they are stopped by something—ideally a seatbelt or airbag.
• The occupant's internal organs slam up against their skeletal structure, which can cause internal injuries due to the rapid deceleration force.

With that in mind, the correct answer to the question is d) All of the above. Modern vehicles are designed to absorb some of the impact and extend the time over which the collision occurs—a concept explained by impulse and momentum change theories in physics. This design includes features like dashboard padding, airbags, and crumple zones, which lessen the force transmitted to the occupants of the vehicle and thus reduce potential injuries.

Answer 2

In a collision all of the things mention above occur. Thus option D is correct.

Step-by-step explanation:

In a collision, multiple forces come into play simultaneously, impacting both the vehicle and its occupants. When a vehicle collides with an object (as stated in option b), it undergoes rapid deceleration, causing the occupants to experience forces that can lead to various impacts (as mentioned in options a and c). Newton's first law of motion states that an object in motion tends to stay in motion unless acted upon by an external force. During a collision, the vehicle comes to an abrupt stop, but the occupants continue moving due to inertia, leading to internal organs slamming against the skeletal structure (option a) and occupants hitting the interior parts of the vehicle (option c).

The force exerted on the occupants can be calculated using Newton's second law of motion, F = ma, where F is the force, m is the mass, and a is the acceleration experienced during the collision. The force of impact depends on the mass of the occupant and the rate at which the vehicle decelerates upon collision. Furthermore, the distribution of force varies based on whether the occupant is restrained by a seatbelt or airbag deployment, affecting the extent of impact on internal organs and the interaction with the vehicle's interior components.

Ultimately, a collision involves complex interactions between the vehicle, the object it collides with, and the occupants, resulting in various forces acting upon internal organs, the skeletal structure, and the contact between occupants and interior vehicle parts. Understanding these dynamics is crucial for designing safer vehicles and implementing effective safety measures to minimize injury risks during collisions. Thus option D is correct.
