dude it cant be 5, the lines of 5 and 14 cant be of the same length, well here is the bloody question
View attachment 91540

Here, you can only derive the angle between V1 with x-axis, which is 37 degrees. Sin(37 degrees)=0.6=3/5, Sin(53 degrees)=0.8=4/5 and the information is not enough to derive the V1 magnitude, unless you make an assumption about having the same length in Y or X-axis with V2 or something like that.
I don't wanna scare you, but this stuff are really simple and easy. You need to already know these stuff. If you don't, either change your major from engineering(if you are an engineering student) or put your *** on the chair and start studying math for 24/7 from now on.

but if this is so simple, why couldnt you find the magnitude yourself LOL

Because the information is not enough. Can't you notice that?
Try to post an image from all of the question, then we may see what are the assumptions of the question.

i think the first part is also referring to the image below

What is the above problem? I mean Q#03?

O_O dude, well here are Q 1,2,3.

Dude i keep asking to you , what the hell question is ?? which operator we are going to use, ??

@XenoEnsi-14 i keep tellin the info is missing what you have told is related to cross product of known vectors to find angles between.

@rmi5 we even tried to solve this problem without knowing what to do, at least now its clear V2-V1 is asked.

@Jf Thunder , i guess you just need to understand how to read problems , rather than solving at 1st.

X might be just a number, it tells Reg. No. might be some digits from your student identification number?

yes, it is 31, i did question no 1, using X = 31, but it is not defined in Q no 4, so i cant use my Reg no for Q 4, obviously

now i have given you the whole assignment, figure it out PLEASE

 

[rmi5]

V=V2-V1
Vx = -7 - 0.8X
Vy= 7Sqrt(3) - 0.6X

Theta=ArcTan(7Sqrt(3) - 0.6X/-7 - 0.8X)
|V|=Sqrt{ (-7 - 0.8X)^2+(7Sqrt(3) - 0.6X)^2 }

Replace your X=31 here and derive your answer

but it is not defined in Q no 4, so i cant use my Reg no for Q 4, obviously

X is the damn 31

but but but, isnt X = Reg no, only allowed for Q 1?

 

[rmi5]

but but but, isnt X = Reg no, only allowed for Q 1?

No, it is for all of the 4 questions.

 

[Jf Thunder]

No, it is for all of the 4 questions.

dude, when i finish this assignment, and i get a "zero" you are gonna be the one who i will be coming after.
now tell me how to find then angle V1 makes with the x axis

nope still didnt get how you got 37 degrees, LOL
sorry bout that
