Final answer:
The contributing factors to the limits of high-magnitude deceleration include crash safety systems like seatbelts and airbags, the use of crumple zones in vehicles, and the physical limits of the human body, such as bone strength(option b).
Step-by-step explanation:
The contributing factors to the limits to high-magnitude deceleration on the human body are primarily based on the physics of impulse and the body's physiological limits.
Crash safety systems, such as seatbelts and airbags, serve to extend the time over which a deceleration occurs, reducing the force exerted on the body per the impulse equation Fnet Δt = Δp, where Δp is the change in momentum and Δt is the time over which the force is applied. These systems mitigate the forces during a vehicular collision, and the use of materials that crumple increases the collision time further. However, the human body has limits, and bones can fracture if subjected to forces that are too large. Factors such as the environment inside the car, the quality of the safety devices, and the physical condition of the individual also play crucial roles.
Therefore, the correct answer is B) Seatbelt quality and airbag deployment.
