Question

how fast does a car airbag come out in a crash?

will vary depending on vehicle speed

65 mph

100 mph

200 mph

Explanation:

Analyze airbag deployment mechanics

Airbags are designed to inflate extremely rapidly to protect occupants before they strike the vehicle's interior during a collision. This rapid inflation is achieved through a controlled chemical reaction that generates gas, causing the airbag to deploy in a fraction of a second.

Determine deployment speed

To be effective, an airbag must fully inflate within approximately 30 to 40 milliseconds. To achieve this speed, the airbag fabric expands outward at speeds ranging from 100 mph to 200 mph. In standard driver education and Vehicle Safety curricula, the typical speed cited for airbag deployment is up to 200 mph.

Evaluate the given options

• "will vary depending on vehicle speed": Incorrect. The deployment speed of the airbag itself is determined by the chemical expansion rate, not the speed of the car.
• "65 mph": Incorrect. This is too slow to protect occupants in a rapid crash.
• "100 mph": Incorrect. While some side airbags or newer smart systems may deploy at lower speeds, standard frontal airbags deploy much faster.
• "200 mph": Correct. This is the standard speed taught in driver safety courses to emphasize the force of deployment and the importance of sitting at least 10 inches back from the steering wheel.

Answer:

• (A) will vary depending on vehicle speed
• (B) 65 mph
• (C) 100 mph
• (D) 200 mph (Correct answer)
