SUMMARY
The average force acting on a 1150kg airplane during its acceleration to a takeoff speed of 31m/s over 7.3 seconds is calculated using Newton's second law, F = ma. The correct calculation involves determining the acceleration first, which is 31m/s divided by 7.3 seconds, resulting in an acceleration of approximately 4.25 m/s². Multiplying this acceleration by the mass of the airplane yields an average force of 4883.6N, confirming the initial calculation was accurate.
