in a car, how does an air - bag minimize the force acting on a person during a collision?\nit increases the…

Brief Explanations:

According to the impulse - momentum theorem $F\Delta t=\Delta p$. The change in momentum $\Delta p$ of a person in a car collision is determined by the initial and final states of motion and is fixed for a given situation. An air - bag increases the time $\Delta t$ it takes for the person to stop. Since $F = \frac{\Delta p}{\Delta t}$, when $\Delta p$ is constant and $\Delta t$ increases, the force $F$ acting on the person decreases.

Answer:

It increases the time it takes for the person to stop.
