Chapter 3, Problem 23A

If a woman has a mass of 50 kg, calculate her weight in newtons.

To determine

Theweight of a woman in Newton.

Answer to Problem 23A

The weight of the woman in Newton is $490\text{}\text{N}$.

Explanation of Solution

Given:

A woman has a mass of 50 kg.

Formula used:

The weight of an object is the force it experiences due to the force of gravity exerted by earth on it. It can be expressed as,

  $W=mg$

Here, mass is expressed in kilograms and the acceleration due to gravity on earth is considered that is $g=9.8{\text{ m/s}}^2$

Calculation:

The mass of the woman is given as 50 kg. Therefore, the weight in Newton is given by,

  $\begin{array}{c}W=50\times 9.8\\ =490\text{ N}\end{array}$

Conclusion:

The weight of woman in Newton is 490 N.
