Using the equation for Impulse, can you explain the following: Why are car steering rods designed to collapse?
Why are highway guard rails designed to crumple up on impact?
Why are traffic safety barrels filled with water or sand?

Answer :

The equation of impact is shown the impulse.

Explanation :

Given that,

The following statements are,

(I). Why are car steering rods designed to collapse?

(II). Why are highway guard rails designed to crumple upon impact?

(III). Why are traffic safety barrels filled with water or sand?

We know that,

The equation of impact is shown the impulse.

Impulse :

Impulse is equal to the change in momentum.

In mathematically,

Where, = change in momentum

F = force

= change in time

We can be minimized of force of impact by maximizing the time of impact.

We can explain the following statements,

(I). Car steering rods designed to collapse for increases the time of impact, decreases the force of impact and reduce the damage caused

(II). Highway guard rails designed to crumple upon impact for increases the time of impact, decreases the force of impact and reduce the damage caused

(III). Traffic safety barrels filled with water or sand because they are increased the time impact.

Hence, The equation of impact is shown the impulse.

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.
