If its mass is 3.55×105 kg and the net braking force is 4.05×105 n , what is the airplane's acceleration? mastering physics

Explanation:

We can find the airplane's acceleration by using Newton's second law of motion, which states that:

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:
