Chapter SH, Problem 14.3APP

To determine

To calculate: Mass of a person.

Answer to Problem 14.3APP

Mass of the person is $\underset{\_}{70\text{ kg}}$ .

Explanation of Solution

Given:

Weight = $686\text{ N}$

Formula used:

Force is given by,

  $F=mg$

where m is mass and $g=9.8\text{ N/kg}$is acceleration due to gravity.

Calculation:

Mass is calculated as:

  $\begin{array}{l}F=mg\\ m=\frac{F}{g}\\ m=\frac{686\text{ N}}{9.8\text{ N/kg}}\\ m=70\text{ kg}\end{array}$

Conclusion:

Mass of the person is $\underset{\_}{70\text{ kg}}$ .
