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?\nit extends the time of the collision.\nit reduces the time of the collision.\nit eliminates the reaction force of the object.\nit eliminates the action force of the object.

Answer

Brief Explanations:

According to the impulse - momentum theorem $J = F\Delta t=\Delta p$. When a player collides, the change in momentum $\Delta p$ is fixed for a given situation. Padding increases the time interval $\Delta t$ of the collision. Since $F=\frac{\Delta p}{\Delta t}$, increasing $\Delta t$ decreases the average force $F$ exerted on the head, reducing injuries.

Answer:

It extends the time of the collision.
