Many vehicles are designed with crumple zones. How does this feature protect the passengers in the vehicle?
Answer)
Many vehicles are designed with crumple zones so that they can crush in a controlled way in a collision. Crumple zones reduces the force involved by increasing the time taken to change the momentum of the driver in a crash situation.

Good luck!:)

Car bumpers and bicycle helmets are designed to crumple / compress upon impact. Use the work-kinetic energy theorem or the impulse-momentum theorem to explain how this serves to protect the people / head inside.
The front 1.20 m of a 1500 kg car is designed as a "crumple zone" that collapses to absorb the shock of a collision. (a) If a car traveling 25.0 m/s stops uniformly in 1.20 m, how long does the collision last? _____ s (b) What is the magnitude of the average force on the car? _____ N (c) What is the acceleration of the car? Express the acceleration as a multiple of the acceleration of gravity. _____g
The front 1.25 m of a 1385-kg car is designed as a ‘crumple zone’ that collapses to absorb the shock of a collision. If a car travelling 27.2 m/s stops uniformly in 1.28 m, a) how long does the collision last, b) what is the magnitude of the average force on the car, and c) what is the acceleration of the car? Express the acceleration as a multiple of the acceleration due to gravity.

Background Distracted driving of motor vehicles has public health implications for drivers, passengers and pedestrians. Accordingly, many states have enacted laws making it illegal to use a mobile phone while driving. Proposition The United States Government should make it illegal to hold a mobile phone while driving a motor vehicle. Where Do You Stand? State whether you strongly agree, agree, disagree, or strongly disagree with the proposition. Explain why.
