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

Answer:

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

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
