In a car collision, the driver's body must change speed from a high value to zero. this is true whether or not an airbag is used, so why use an airbag? how does it reduce injuries

1. If I had my choice, I'd much rather crash into an airbag than a windshield.
2. When it inflates, it minimizes the distance you are going to travel. If a windshield is 2 feet away and you're heading right for it, an airbag would stop you before you hit the windshield by taking up the space between you and the (hopefully avoided) object.

Ibelieve the answer is d. macula  hope my answer has you : )
