Chapter 6: Q.17 (page 155)

A woman has a mass of 55 kg.
a. What is her weight while standing on earth?
b. What are her mass and her weight on Mars, where g = 3.76 m/s2 ?

Short Answer

Expert verified

a. $W_{1} = 539.55 N$

b. $W_{2} = 206.8 N$

Step by step solution

Content Introduction

Inertia is a fundamental feature of all matter, and mass is a quantitative measure of it. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force. The smaller the change caused by an applied force, the larger the mass of the body.

Explanation (Part a)

We are given:

$g_{2} = 3.76 m / s^{2} m = 55 k g$

The weight of body is equal to:

$W_{1} = m . g W_{1} = 55 k g (9.81 m / s^{2}) W_{1} = 539.55 N$

Explanation (Part b)

The mass of the body does not change wherever the body is at.

$m = 55 k g W_{2} = m \times g_{2} W_{2} = 55 k g (3.76 m / s^{2}) W_{2} = 206.8 N$
