Answer:
a = 1.875 [m/s²]
Explanation:
The plane begins to move from rest to reach the take-off speed, by means of the following equation of kinematics we can calculate the acceleration.
[tex]v_{f}^{2} =v_{o}^{2}+2*a*x\\[/tex]
where:
vf = final velocity = 30 [m/s]
vo = initial velocity = 0
a = acceleration [m/s²]
x = distance = 240 [m]
[tex](30)^{2}=0 +2*a*240\\900=480*a\\a=1.875 [m/s^{2} ][/tex]
