Best ResponseYou've already chosen the best response.3velocity of jet is 775 mi/h in NE direction : dw:1433303568557:dw

Best ResponseYou've already chosen the best response.3can you split it as horizontal and vertical components ?

Best ResponseYou've already chosen the best response.1you mean like make it into triangles?

Best ResponseYou've already chosen the best response.3Yes solve these two sides in the right triangle dw:1433304188744:dw

Best ResponseYou've already chosen the best response.1the side along j is 548.007 ...right?

Best ResponseYou've already chosen the best response.1no, sorry. the side from the j line to the plane

Best ResponseYou've already chosen the best response.3so for part \(b\), the velocity of jet in component form is \[\large 548i + 548j\]

Best ResponseYou've already chosen the best response.1can we do the same for the wind and get 27.5? or does that not work?

Best ResponseYou've already chosen the best response.3you need to work horizontal and vertical components in this triangle dw:1433306300948:dw

Best ResponseYou've already chosen the best response.3horozontal = 55*sin(30) = ? vertical = 55*cos(30) = ?

Best ResponseYou've already chosen the best response.1(horizontal first, vertical second)

Babynini

Best ResponseYou've already chosen the best response.1is the direction of the jet (the last box) = 58.64?

Best ResponseYou've already chosen the best response.1(sorry, tht's a completely different part. we can come back to that.)

Best ResponseYou've already chosen the best response.3good so for part \(a\) do we have \[\large 27.5i + 47.63j\] ?

ganeshie8

Best ResponseYou've already chosen the best response.3For part \(c\), simply add the answers from part \(a\) and \(b\)

Best ResponseYou've already chosen the best response.3hey may be use 548.0077i + 548.0077j for part a because they are asking to round to two decimal places

ganeshie8

Best ResponseYou've already chosen the best response.3part \(c\) : true velocity of plane = velocity of plane + velocity of wind = \(\large (548.007i+548.007j) + (27.5i+47.63j)\) = ?

Best ResponseYou've already chosen the best response.3you should be getting 575.51i +595.6\(\color{red}{4}\)j check once

Best ResponseYou've already chosen the best response.1hm ok. Maybe i rounded the numbers wrong. I tried to use the original numbers.

ganeshie8
 one year ago
Best ResponseYou've already chosen the best response.3ok part \(d\) should be simple take the magnitude of true velocity vector from part \(c\)

ganeshie8

Best ResponseYou've already chosen the best response.3speed = \(\575.51i+595.64j\ = \sqrt{575.51^2+595.64^2}=?\)

Best ResponseYou've already chosen the best response.3knw how to work last part ?

Babynini
 one year ago
Best ResponseYou've already chosen the best response.1uh well I think so but i've been getting lots wrong lately lol

ganeshie8

Best ResponseYou've already chosen the best response.3for last part, just need to find the angle of true velocity vector from part \(c\)

Babynini

Best ResponseYou've already chosen the best response.1equation for that would be?

ganeshie8

Best ResponseYou've already chosen the best response.3For any vector \(x+iy\), angle with positive x axis is given by \(\tan^{1}(y/x)\)

Babynini

Best ResponseYou've already chosen the best response.1so we'd do tan^(1) 595.64/575.51

Best ResponseYou've already chosen the best response.3yes use ur calculator

Babynini

Best ResponseYou've already chosen the best response.1oh but rounded to nearest interger so 46?

ganeshie8

Best ResponseYou've already chosen the best response.3yes but thats the angle from positive x axis : dw:1433308877835:dw

ganeshie8

Best ResponseYou've already chosen the best response.3the question is asking you for the angle from positive "y" axis

Best ResponseYou've already chosen the best response.1Did i put them in wrong? o.o because the answers based off of those are correct.

Best ResponseYou've already chosen the best response.3how many chances do u have ?

ganeshie8

Best ResponseYou've already chosen the best response.3try putting exact form

Best ResponseYou've already chosen the best response.1oh gosh no lol just 5.

Best ResponseYou've already chosen the best response.3part \(a\) : \[\large 27.5i+27.5\sqrt{~3~} j\]

Best ResponseYou've already chosen the best response.3part \(b\) : \[\large 387.5\sqrt{2}i+387.5\sqrt{2}j\]

Best ResponseYou've already chosen the best response.1Yeah the example one they did looks sort of like that. just divided b by the sq2

ganeshie8

Best ResponseYou've already chosen the best response.3good, give it a try you have 3 more chances right

Best ResponseYou've already chosen the best response.1so should I do it exactly like them and try to put little arrows over stuff?

ganeshie8
 one year ago
Best ResponseYou've already chosen the best response.3do u knw how to put arrows ?

ganeshie8
 one year ago
Best ResponseYou've already chosen the best response.3maybe forget about arrows for now and try entering the exact values wid radicals if it doesn't work, then you may try with arrows

ganeshie8
 one year ago
Best ResponseYou've already chosen the best response.3because part c worked even when you didn't put arrows

Babynini
 one year ago
Best ResponseYou've already chosen the best response.1not dividing it by sq2 either?

ganeshie8

Best ResponseYou've already chosen the best response.3enter these and let me know if they work http://gyazo.com/81f10a84809d5f9dc852b18b923080a3
