Chapter 24.3, Problem 20R

To determine

To calculate: Mass of the new satellite.

Answer to Problem 20R

Mas of new satellite = $\underset{\_}{7500\text{ kg}}$ .

Explanation of Solution

Given info:

Mass of satellite = $\text{10000 kg}$

Reduction in mass = $\text{25\%}$

Calculation:

Reduction in mass is calculated as,

  $\begin{array}{l}\text{25\% of 10000 kg}\\ \text{=}\frac{\text{25}}{100}\text{ of 10000 kg}\\ \text{= 2500 kg}\end{array}$

Mas of new satellite = $\text{10000 kg}-\text{2500 kg}=7500\text{ kg}$

Conclusion:

Mas of new satellite = $\underset{\_}{7500\text{ kg}}$ .
