A 95.0 kg person is driving along at 30.0 m/s in the positive x-direction. The car hits a wall and is stopped. The airbag deploys. The person’s impact with the airbag lasts for just 225.0 milliseconds. What is the momentum of the person just before impact? What is the momentum of the person just after impact? What is the change in the person’s momentum? Over what time interval does the change in the person’s momentum occur? What is the average force exerted on the person by the airbag during the impact? A person stands a good chance of surviving an impact of 10 g’s or less. A person stands little chance of surviving an impact of 20 g’s or greater. A person stands almost zero chance of surviving an impact of 50 g’s or greater. Rate this person’s chance at surviving this impact.

Question

A 95.0 kg person is driving along at 30.0 m/s in the positive x-direction. The car hits a wall and is stopped. The airbag deploys. The person’s impact with the airbag lasts for just 225.0 milliseconds.

    1. What is the momentum of the person just before impact?
    2. What is the momentum of the person just after impact?
    3. What is the change in the person’s momentum?
    4. Over what time interval does the change in the person’s momentum occur?
    5. What is the average force exerted on the person by the airbag during the impact?
    6. A person stands a good chance of surviving an impact of 10 g’s or less. A person stands little chance of surviving an impact of 20 g’s or greater. A person stands almost zero chance of surviving an impact of 50 g’s or greater. Rate this person’s chance at surviving this impact.
