football helmets are made with padding that helps reduce head injuries when a player collides with an object. which best explains how the padding reduces injuries?\no it extends the time of the collision.\no it reduces the time of the collision.\no it eliminates the reaction force of the object.\no it eliminates the action force of the object.
Answer
Brief Explanations:
According to the impulse - momentum theorem $J = \Delta p = F_{avg}\times\Delta t$. When the padding in a football helmet is present, for a given change in momentum ($\Delta p$), by extending the time of the collision ($\Delta t$), the average force ($F_{avg}$) experienced by the head is reduced, thus reducing injuries. The reaction and action forces cannot be eliminated as per Newton's third law.
Answer:
It extends the time of the collision.
