Answer:

Acceleration of the plane, a=-2.14\ m/s^2

Explanation:

It is given that,

Initial speed of the airplane, u = 245 m/s

Final speed of the airplane as it slows down, v = 230 m/s

It took the pilot 7 seconds to get down to its final speed. Let a is the acceleration of the plane. We know that the rate of change of velocity of an object is called its acceleration. The mathematical expression is given by :

a=\dfrac{v-u}{t}

a=\dfrac{(230-245)\ m/s}{7\ s}

a=-2.14\ m/s^2

The negative sign shows that the airplane is slowing down or deceleration. Hence, this is the required solution.
