Question

A jet with mass m = 6 × 104 kg jet accelerates down the runway for takeoff at 1.9 m/s2.1) what is the net horizontal force on the airplane as it accelerates for takeoff?

Answer 1

Net horizontal force on the airplane as it accelerates for takeoff = 1140 kN

Step-by-step explanation:

The force on any body can be defined as product of mass and acceleration

That is Force, F = ma

In this case mass of jet, m =
`6*10^4kg` and acceleration of jet, a =
`1.9m/s^2`.

Substituting in the above equation we have

Force, F =
`6*10^4*1.9` =
`11.4*10^5 N = 1140 kN`

So, net horizontal force on the airplane as it accelerates for takeoff = 1140 kN
