A jet plane pilot decides to accelerate horizontally. If the thrust of the engine is increased to 50 000 N at a time when the air resistance ( or drag) acting on the 4000kg plane amounts to 30 000 N , what will the planes acceleration be

I believe you at the 50 000 and the 30 000 N to get f net, then 4000 kg is the mand , then just put the numbers into the equation a= fnet/m ? Am i on the right track?

    Sorry i meant 4000 kg is the mass

  • physics - ,

    yes
    50,000 - 30,000 = fnet = m a
    so
    a = 20,000/4000 = 20/4 = 5 m/s^2
