Chapter 5, Problem 120AP

Interpretation Introduction

Interpretation:

Using mechanics and the first law of thermodynamics, the statement,“Stopping distance quadruples as the speed doubles,” is to be justified.

Concept introduction:

The first law of thermodynamics is based on the law of conservation of energy. It states that energy can be converted from one form to another but cannot be created or destroyed.

Kinetic energy is the energy thatis created from the motion of the body.

Kinetic energy is calculated as

$E_{\text{k}}=\frac{1}{2}m{u}^2$

Here, $E_{\text{k}}$ is the kinetic energy, m is the mass, and u is the velocity of the object.
