and



Presuming a standing start, , so solving



for gives the amount of time it takes the aircraft to attain a speed of 35 m/s with an acceleration of 3 m/s²

Then, knowing the value of , the distance traveled in seconds at a constant acceleration of 3 m/s² with an initial velocity of zero and an initial distance of zero is given by:



Plug in the value of calculated above and then do the arithmetic.

My calculator said it, I believe it, that settles it
