Cars are equipped with padded dashboards. in collisions, the padded dashboards would be safer than non-padded ones because they (consider the impulse-momentum theorem: f▲t = m ▲v .)

group of answer choices

increase the impact time

increase the impact force

increase the impact velocity

none of these.

In collisions, the padded dashboards would be safer than non-padded ones because they increase the impact time.

Option A

Explanation:

The padded dashboards will prevent the direct impact effect on the passenger as the impact will be absorbed by the pad. And moreover, there will be delay on action of impact on the passenger due to the padded dashboard.

As the dashboard will be giving a force in opposite direction to the impact force, so the opposing force of the padded dashboard will prevent the passenger to fall directly on the windshield with the complete impact force. Instead it will make the passenger fall after some time with the decrease in the impact force due to the loss of force with time.
