Chapter 6, Problem 55A

What is the acceleration during takeoff of a jumbo jet with a mass of 30,000 kg when the thrust for each of its four engines is 30,000 N?

To determine

Acceleration during takeoff.

Answer to Problem 55A

  $a=1{\text{m/s}}^2$

Explanation of Solution

Given:

Thrust of the four engines, $F=30000\text{N}$

Mass of jumbo jet, $m=30000\text{kg}$

Formula Used:

From Newton’s second law, the net force is given as

  $F=ma$

Where, $m$ is mass of object and $a$ is acceleration.

Calculation:

On substituting the given values,

  $\begin{array}{l}30000=30000\times a\\ \Rightarrow a=\frac{30000}{30000}=1\\ \Rightarrow a=1{\text{m/s}}^2\end{array}$

Conclusion:

Therefore, the acceleration during takeoff is $a=1{\text{m/s}}^2$ .
