Calculate Jet Engine Thrust for 800 kg Jet Takeoff with 4 m/s^-2 Acceleration

[BIGEYE]

Homework Statement

Calculate the engine thrust required to produce an acceleration of 4 m/s^-2 in a jet of mass 800 kg as it takes off along the runway. The air resistance is 500 N
Appreciate if anyone can check if I have used the correct equation, and my answer.

Homework Equations

F - R = ma

The Attempt at a Solution

F - R = 800 x 4
F - 500 = 3200
Thrust (F) = 3700 N
