I have a physics question? So confused :(
I am so confused :(
I am taking basic physics
Rochelle is flying to New York for her big Broadway debut. If the plane heads out of Los Angeles with a velocity of 220 meters/ second in a northeast direction, relative to the ground, and encounters a wind blowing head-on at 45 meters/ seconds, what is the resultant velocity of the plan, relative to the ground?

Maybe I'm confused also.
Assuming that the plane doesn't speed up to maintain it's velocity relative to the ground. Assuming that the wind blowing head-on actually is absorbed 100% by the plane. I would think that the plane is only moving at 220 - 45 = 175 meters / s relative to the ground.
But it's been many many moons since I took physics.
Good Luck.

Thank you. This answer was right.
It looks like a simple matter of subtracting the head-on wind velocity from the velocity of the plane. The "NE direction" part is not relevant to the question and is probably placed there to mislead. :
No need to be confused. The answer that pazaq gave is correct according to this identical yahoo question and answer.
The direction of the plane only isn't relevant because the wind is head on by the way. I would expect a follow up question from your instructor where this is not the case so be on the lookout.

The question states the planes relative velocity to the ground:
"If the plane heads out of Los Angeles with a velocity of 220 meters/ second in a northeast direction, relative to the ground,"
Nothing is going to change that. So the answer is: 220 meters/ second in a northeast direction
The instructor probably meant "what is the resultant velocity of the plane, relative to the air?", which you would just add the two velocities.
