Using newtons second law
Answer:
The answer is 3.33m
Explanation:
The acceleration "a" is constant.
Acceleration is the variation of velocity over time,
.
solving the last equation
,
where because the airplane starts from rest.
Once again, velocity is the variation of distance over time.
then
where if we consider the end of the runway as the initial point (this step is for simplicity but you can let it expressed, it's going to cancel anyway).
If at
, then
and the final expression for the distance is
.
If t = 2s, x = 4.44 m. Which means thad the additional distance is
