The length of the runway of the airfield is 1400 m. What is the acceleration of the aircraft if the speed

The length of the runway of the airfield is 1400 m.What is the acceleration of the aircraft if the speed of its takeoff from the ground is 720 km / h

The acceleration of the aircraft will be found using the formula:

S = (V ^ 2 – V0 ^ 2) / 2a, where S is the length of the runway of the aerodrome (S = 1400 m), V is the speed of the aircraft at the moment of taking off from the ground (V = 720 km / h = 720 * 1000/3600 = 200 m / s), V0 is the aircraft speed at the beginning of acceleration (V0 = 0 m / s), and is the required aircraft acceleration.

S = V ^ 2 / 2a and a = V ^ 2 / 2S.

Let’s do the calculation:

a = 200 ^ 2 / (2 * 1400) = 14.29 m / s2.

Answer: The acceleration of the aircraft is 14.29 m / s2.
