in a car, how does an air - bag minimize the force acting on a person during a collision?\no it increases the change in momentum of the person.\no it decreases the change in momentum of the person.\no it increases the time it takes for the person to stop.\no it decreases the time it takes for the person to stop.
Answer
Brief Explanations:
According to the impulse - momentum theorem $J = F\Delta t=\Delta p$. In a collision, the change in momentum $\Delta p$ of a person is fixed by the initial and final velocities. 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.
