Question

What is the mass of a body whose weight is 59 N? Take $g=9.8\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s^2$}\right.$

Answer 1

Step 1: Given data

Write the expression for weight of body as follows:

$W=mg$

Here, $m$ is mass of body and $g$ is gravitational acceleration.

Step 2:Calculation

Substitute $59\text{N}$ for $W$ and $9.8\frac{\text{m}}{{\text{s}}^2}$ in expression of weight.

$$\begin{gathered} 59\text{N}=m\times 9.8\frac{\text{m}}{{\text{s}}^2} \\ m=\frac{59}{9.8}\text{kg=}6.02\text{kg} \end{gathered}$$

Hence, mass of body is $6.02\hspace{0.17em}\text{kg}$.
