Question

An aircraft on its take off run has a steady acceleration of 3m per second square

Answer 1

Hi there! If an aircraft has a steady acceleration of 3 meters per second squared during takeoff, that means that its speed is increasing by 3 meters per second every second.

For example, if the aircraft starts at rest (0 meters per second) and accelerates at 3 meters per second squared for 10 seconds, its speed at the end of the 10 seconds would be:

Speed = Acceleration x Time

Speed = 3 m/s^2 x 10 s

Speed = 30 meters per second

Answer 2

The steady acceleration of an aircraft during takeoff is 3 m/s². This means that for every second the aircraft is on its takeoff run, its speed increases by 3 meters per second.

To understand this concept better, let's break it down into steps:

1. Acceleration: Acceleration refers to the rate at which an object's speed changes. In this case, the aircraft is accelerating at a constant rate of 3 m/s². This means that its speed increases by 3 meters per second every second.

2. Takeoff run: The takeoff run is the distance covered by the aircraft on the ground before it becomes airborne. During this phase, the aircraft gradually increases its speed until it reaches the speed required for takeoff.

3. Example: Let's say the aircraft starts from rest and accelerates at a steady rate of 3 m/s². After 1 second, its speed would be 3 m/s. After 2 seconds, its speed would be 6 m/s, and so on. The speed keeps increasing by 3 m/s for every second of acceleration.

It's important to note that this example assumes a constant acceleration throughout the takeoff run. In reality, factors such as wind, weight, and runway conditions can affect the acceleration of an aircraft during takeoff.

Overall, the steady acceleration of 3 m/s² means that the aircraft's speed increases by 3 meters per second for every second it spends on its takeoff run.
