Chapter 14.1, Problem 3LC

Interpretation Introduction

Interpretation: To determine the reason why a collision with an airbag causes less damage than a collision with a stirring wheel.

Concept Introduction: A collision occurs when two things briefly come into touch with one another. In other terms, a collision would be a reciprocal engagement between two masses that lasts for a relatively brief time and results in a change in momentum as well as energy between both two masses.

Answer to Problem 3LC

Gas can be easily compressed whereas solid cannot be compressed. Hence, cause less damage.

Explanation of Solution

A collision with an airbag causes less damage than a collision with a stirring wheel because gas will be compressed and some amount of energy will be absorbed by the bag. It is known that solids cannot be compressed. Hence, it would damage things after the collision.
