Answer:
[tex]a=20\ m/s^2[/tex]
Explanation:
Given that,
Initial speed, u = 0
Final speed, v = 40 m/s
Time, t = 2 s
We need to find the acceleration of the aircraft. We know that, acceleration is equal to the rate of change of velocity. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{40-0}{2}\\\\=20\ m/s^2[/tex]
So, the acceleration of the aircraft is [tex]20\ m/s^2[/tex].
