Chapter 6, Problem 6.4QP

Interpretation Introduction

Interpretation:

The violation in the law of conservation of energy when the truck comes to halt has to be predicted and explained.

Concept Introduction:

The first law of thermodynamics states that energy can be either destroyed or created but instead it can be converted from one form to other.  The first law of thermodynamics is modified version of law of conversion of energy for a thermodynamic system.  The total energy of system that is isolated is constant.

The equation for the first law of thermodynamics is given by,

${\text{U=U}}_{\text{f}}{\text{-U}}_{\text{i}}$

Where U=total energy of the system

${\text{U}}_{\text{f}}$ = final energy

${\text{U}}_{\text{i}}$ = initial energy
