The average force applied by the ground on the Aeroplane is 16.664 kN.

<h3>What is Newton's second law of motion?</h3>

It states that the force F is directly proportional to the acceleration a of the body and its mass.

F =ma

Given is the mass of aeroplane, m =400 kg and the velocity v = 5000 m/s,

It takes t = 2 min to come to rest, then the acceleration will be

a = velocity /time

a = 5000/(2x60)

a = 41.66 m/s²

According to the Newton's second law of motion.

F = 400 kg x 41.66 m/s²

F = 16.664 kN

Thus, the average force applied by ground on aeroplane is 16.664 kN
