Question

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?
A) It extends the time of the collision


B) It reduces the time of the collision 


C) It eliminates the reaction force of the object


D) It eliminates the action force of the object.

Answer 1

Answer: A It extends the time of the collision.

Explanation:

Answer 2

In padding helmets we have pads or cushions on it which will move inwards when ball hits the helmets

Now due to this the collision time will increase and ball is not immediately rebound with the helmets

so as we know the Newton's law

$F = \frac{\Delta P}{\Delta t}$

so here if collision time is increased then we will have less force

so the impact of collision will be less

So the correct answer will be

A) It extends the time of the collision
