Answer:

a = -56000 Km/h²

Step-by-step explanation:

Given,

The initial speed of the plane, u = 738 Km/h

The final speed of the plane, v = 30 Km/h

The time period of the travel, t = 0.013 h

The acceleration of a body equal to the difference between the final and initial velocity to the time period of travel.

The formula for acceleration,

a = (v - u) / t

= (30 - 738) / 0.013

= -56000 Km/hr²

The negative sign indicates that the plane is decelerating.

The acceleration of the plane is, a = -56000 Km/hr²
