Jet engine thrust

  1. Jan 21, 2007 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    F - R = ma


    3. The attempt at a solution
    F - R = 800 x 4
    F - 500 = 3200
    Thrust (F) = 3700 N
