The acceleration of the air plane is 
<u>Explanation:</u>
Given:
The mass of the air plane = 1492.3 kg
Force of each four engine = 1447.5 N
So, the total force of four engines can be calculated as = 4(1447.5) = 5790 N
The force that acts on the object is equal to the product of mass (m) and its acceleration. It can express by the below formula,

The above equation can be written as below to find acceleration,

Now. Substitute the given values, we get,

Answer:
velocity in which the space described varies from instant to instant, either increasing or decreasing in the former case called accelerated velocity
