An airbus a350 is initially moving down the runway at 6.0 m/s preparing for takeoff. the pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.8 m/s^2. the plane then travels a distance of 1500 m down the runway before lifting off. how long does it take from the application of the acceleration until the plane lifts off, becoming airborne?

t=67.7s

Explanation:

From this question we know that:

Vo = 6m/s

a = 1.8 m/s2

D = 1500m

And we also know that:

  Replacing the known values:

   Solving for t we get 2 possible answers:

t1 = -44.3s   and t2 = 67.7s    Since negative time represents an instant before the beginning of the movement, t1 is discarded. So, the final answer is:

t = 67.7s
