Chapter 2, Problem 2.17P

Interpretation Introduction

(a)

Interpretation:

The mass in slugs and the weight in poundals of a 135 lb_m woman (i) on earth and (ii) on the moon should be determined.

Concept introduction:

According to Newton’s second law

$\text{F = ma}$

Where,

$F$ = force $m$ = mass and $a$ = acceleration

$1l{b}_m\times 1ft/s^2=\frac{1}{32.174}l{b}_f$

Interpretation Introduction

(b)

Interpretation:

The rate at which the object accelerates should be determined.

Concept introduction:

According to Newton’s second law

$F=ma$

$1poundal=1l{b}_m\times 1ft/s^2=\frac{1}{32.174}l{b}_f$

$1slug=32.174l{b}_m$
