Answer:
[tex]-1.14 m/s^2[/tex]
Explanation:
We can find the airplane's acceleration by using Newton's second law of motion, which states that:
[tex]F=ma[/tex]
where
F is the net force on the airplane
m is the mass of the airplane
a is its acceleration
The problem says that the force is a braking force, so this means that the airplane is slowing down, therefore the acceleration must be negative and we must put a negative sign in front of the force. Re-arranging the equation, we can find the acceleration:
[tex]a=\frac{F}{m}=\frac{-4.05\cdot 10^5 N}{3.55\cdot 10^5 kg}=-1.14 m/s^2[/tex]
