SUMMARY
In a head-on collision, a car decelerates from a speed of 22 m/s to 0 m/s in 0.18 seconds. Given the driver's mass of 75 kg, the force exerted by the seat belt can be calculated using Newton's second law. The resulting force applied to the driver by the seat belt during this brief period is approximately 8,333.33 N, demonstrating the significant impact of seat belts in mitigating injury during collisions.
