resultant velocity of a plane=80-10
=70m/s
The resultant velocity of a plane is 75 km/hr.
This question is a perfect case where it's important to somehow describe the "reference frame" in which a particular speed is measured.For example, if the "200 meters per second" is the plane's AIRspeed, then as long as the fuel holds out,that speed doesn't change, no matter what kind of air the plane flies through.It's clear that this question is interesting only if all the speeds are measured relative to the GROUND.If the plane's groundspeed is 200 meters per second, and it encounters a wind that's blowingacross the ground at 50 meters per second in the opposite direction, then the plane's groundspeedbecomes 150 meters per second.
The resultant velocity is calculated by subtracting the headwind velocity from the airplane's velocity: 1400 kph (west) - 20 kph (east) = 1380 kph (west)
A headwind hitting a plane
It would consume more fuel - as it would need to expend more energy to fight against the headwind.
A headwind blows directly opposite to the direction of travel. For instance, if you are moving forward, a headwind will come from the front, making it more challenging to move forward. It can affect various activities, including flying and cycling, by increasing resistance against the direction of motion.
yes
In athletics a headwind is expressed in negative terms eg - 5 m/s a wind in your face of 5 metres per second. A tailwind is expressed in positive terms eg + 5 m/s. The positive & negative seem superfluous as a headwind and tailwind are self explanatory
The groundspeed would be 175 knots. This is calculated by subtracting the headwind component (25 knots) from the True Airspeed (200 knots).
I think you would mean a kesterel.
Increase headwind component.
It is difficult for the same reason it takes more of a physical effort to cycle against a headwind. A headwind is trying to push us backwards, slowing our forward progress. With a tailwind, the wind is helping us to row a boat or cycle faster as it pushes us along from behind. A headwind causes air friction to increase.
