what happens to the speed of an airplane with a 25 km/h tailwind pushing ahead from tail to front?
When an airplane is flying with a tailwind, which means the wind is blowing in the same direction as the plane's flight path, it will have an effect on the plane's speed.
To understand what happens to the speed of the airplane, let's break it down:
1. The airplane's airspeed: This refers to the speed of the airplane through the air without taking the wind into account. It is the speed measured by the airplane's instrument, typically in kilometers per hour (km/h).
2. The wind speed: This is the speed at which the wind is blowing relative to the ground, also usually measured in km/h.
3. The tailwind: In this scenario, the airplane is flying with a 25 km/h tailwind. This means that the wind is pushing the airplane from behind, in the same direction as its flight.
To determine the resulting ground speed (the speed of the airplane relative to the ground):
Ground speed = Airspeed + Wind speed (when flying with a tailwind)
In this case, the airplane's ground speed will be the sum of its airspeed and the 25 km/h tailwind.
For example, let's say the airplane has an airspeed of 200 km/h. With the 25 km/h tailwind pushing it forward, the ground speed would be:
Ground speed = 200 km/h + 25 km/h = 225 km/h
So, the airplane's ground speed would be 225 km/h with the 25 km/h tailwind pushing it ahead from the tail to front.
