Velocity Magnitude
If a jet is traveling 200 mi/hr and the tail wind is 40 mi/hour what is the resulting velocity?
I think it is 200+ 40 = 240 magnitude
And is its counter clockwise 240 degrees too?
Am I correct?

Best ResponseYou've already chosen the best response.0If it is 240 it is going South West?

Best ResponseYou've already chosen the best response.0I think the magnitude is 240, but there's no info that allows you to figure out the angle

anonymous

Best ResponseYou've already chosen the best response.0ok. then the angle would be 0°

anonymous

Best ResponseYou've already chosen the best response.0because both the plane and the wind are east

Best ResponseYou've already chosen the best response.0This is what it states. The direction of a vector is often expressed as a counter clockwise angle of rotation of the vector from due east. In such a convention, East is 0 degree, North 90, West is 180 and south 270.

Best ResponseYou've already chosen the best response.0I have to find the Magnitude and the direction

anonymous

Best ResponseYou've already chosen the best response.0oh, gotcha. I thought you were saying that the plane was traveling east. Whatever direction the plane is flying in is the angle because a tail wind by definition is in the direction of travel. dw:1436033950387:dw they have to tell you a direction to start with

Best ResponseYou've already chosen the best response.0Ok, so we are staring with East 0 degree right?

anonymous

Best ResponseYou've already chosen the best response.0they really gave you speeds and asked you to find velocity

Best ResponseYou've already chosen the best response.0Since we have 240 mag, which is a 45 degree we would be going in the direction of north east?

anonymous

Best ResponseYou've already chosen the best response.0Honestly, I don't see how you can get a direction from the information provided. I just put that up there as an example of 2 different directions having the same magnitude

Best ResponseYou've already chosen the best response.0Is there maybe a picture with this problem?

anonymous

Best ResponseYou've already chosen the best response.0Nope, just shows the jet and the wind magnitude

anonymous

Best ResponseYou've already chosen the best response.0Maybe the jet is going east?

anonymous

Best ResponseYou've already chosen the best response.0I'd go with that. really you could go with any direction.

Best ResponseYou've already chosen the best response.0I do have to calculate for Side Wind on the next problem, which will push it at a different angle

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok. that kind of makes sense. as if it's going 0° initially and then the side wind pushes it in another direction

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0still they could have made it more clear by stating explicitly that the direction was due east

anonymous

Best ResponseYou've already chosen the best response.0I have to calculate for Tail, Head and Side Wind... Tail shoud be 240 and Head should be 160 and I have to do the side, which the wind is coming from the north so it will push it South east

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so your angle for the head wind was also 0°?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yes, because it is just pushing toward the jet

anonymous

Best ResponseYou've already chosen the best response.0The side wind is the only thing I see that would make it change from east.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Is the side wind also 40 mph ?

anonymous

Best ResponseYou've already chosen the best response.0Yeah it must be east. It tells us here The direction of a vector is often expressed as a counter clockwise angle of rotation of the vector from due east. In such a convention, East is 0 degree, North 90, West is 180 and south 270

anonymous

Best ResponseYou've already chosen the best response.0Hummm or is it West????

anonymous

Best ResponseYou've already chosen the best response.0Is it going from East to West so the Plane is moving West?

anonymous

Best ResponseYou've already chosen the best response.0I'd stick with east. it really doesn't say and east is a reasonable guess since that's 0

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yeah but it would move at 180 degree since it is moving at a straight line

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0which 180 would be moving West

anonymous

Best ResponseYou've already chosen the best response.0that's kind of what I'm saying. they didn't give you and explicit direction to begin with. When you work a vector problem, it's supposed to say for example 40 mph due east, or 200 mph at 45° SE. They only gave you the magnitudes of the vectors. There's no way for you to figure out the directions. You just have to pick a assume as the starting point and work the rest of the problem with that assumed direction. Picking 0° is just the easiest starting directions

anonymous

Best ResponseYou've already chosen the best response.00 degree is the starting and they stat it is east so if the jet moves with only tail or head wind, it moves at 180 degrees

anonymous

Best ResponseYou've already chosen the best response.0I am assuming this from this passage The direction of a vector is often expressed as a counter clockwise angle of rotation of the vector from due east. In such a convention, East is 0 degree, North 90, West is 180 and south 270

Best ResponseYou've already chosen the best response.0they're both still going to be at 0° because the speed of the plane is greater than both the wind's vectors

anonymous

Best ResponseYou've already chosen the best response.0But if it starts at 0, which it states it is often express as counter clockwise, so a jet moving straight from 0 would be 180

Best ResponseYou've already chosen the best response.0So you would say East. Why they make it so confusing lol

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0yeah I would. I don't know, this is just a really badly worded question

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0What gets me is where it stats from due east like if you are coming from and then going to

anonymous

Best ResponseYou've already chosen the best response.0I always think of the start point as the origin, which makes it a little easier

anonymous

Best ResponseYou've already chosen the best response.0I gotta run. hopefully I was able to give some help. For the sidewind, since it's coming from the north, it will be at a 270° direction

anonymous

Best ResponseYou've already chosen the best response.0Yes, you are always a lot of help
