If the occupant hits the dashboard, known decceleration quickly. To use Decceleration In this case, the Panel violence against the residents, and more power, the greater the risk of injury.
Force = mass x acceleration = mass x change in velocity / time
The weight of the occupant and the change of speed are the same, regardless of the board, just the weather decceleration.
The dashboard has a padded decceleration longer, and thus a lower force.
The residents take to ensure that the hyphen book experience both a reduction of the impact and greater force, so the answer is (E) correctly.
Pulses) is the change in time (= mass × velocity. How to be the same for the two control panels, the answer must be (B) be wrong.
