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

300000 N

Step-by-step 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* 4`

`F=(300000* 4)/(4)=300000N`

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