Question

A 747 jumbo jet of mass 300,000 kg accelerates down the runway at 4 m/s2 . What must be the force generated by each of its four engines

Answer 1

Answer:

300000 N

Explanation:

We are given that

Mass of jumbo jet=300,000kg

Acceleration of jet=$4m/s^2$

We have to find the force generated by each of its four engines.

We know that

Force,F =ma

Total force exert by four engines=4F

$4F=300000\times 4$

$F=\frac{300000\times 4}{4}=300000N$

Hence, the force generated by each of its four engines=300000 N
