In a car accident, the driver of the car is often stopped by either the steering wheel or the airbag. Imagine a 60 kg driver is moving at 20 m/s. If they hit the steering wheel, they come to a stop in 0.03 s. If they hit the airbag, they come to a stop in 0.12 s.
Explain why it is safer to hit the airbag. Discuss the relationship between the force the driver feels, the time of impact, and their change of momentum.
