Acar is traveling at 30 m/s and about to impact on a wall. what change would result in the safest outcome for the passengers in the car?

An increase in the stopping time (collision time) of the car.

Explanation:

The force exerted on the passenger during the collision is given by:

where is the variation in momentum of the passenger and is the stopping time. From this equation, we see that the force is inversely proportional to the duration of the collision: therefore, if the stopping time is increased (and this is what an airbag does), then the force exerted on the passenger is decreased.

terd muffin is the correct answer

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
