i think its A

i think its A

its vector X minus Y right? so u can flip the Y vector in the other direction and add both and wouldnt it look like vector c? Youre right its A but why not C

idk i guessed it, i js put the two arrows together

 

[wollongong warrior]

should be C imo, if we think of Y as being stationary then X should be moving away, not towards Y
it's a stupid question, just move on, there's not even an axis to even base the velocity vectors on

i can't see how its anything but C lmao. what a bonkers question

its A cause if you put the two arrows together you get A

I agree.
I don't now physics and all, but isn't a vector a measure of magnitude and direction? therefore the direction of A is correct, (it could be D too, if you rotate the lines)
Unless there's something i haven't learned T-T

but A is if u add the vectors not subtract them and since its relative velocity it should be subtracted

how do you subtract lines

vector is a measure of magnitude and direction yes, but this isn't questioning what a vector is; it's asking what the velocity of X is relative to Y

oh, thanks.

relative velocity of object relative to observer = velocity of object - velocity of observer
relative velocity of X relative to Y = velocity of X - velocity of Y
that would give you C

 

[kkk579]

its so over

u take phys?

 

[kkk579]

u take phys?

nvm this guy gotta be a troll

The answer is (C). This question has been answered before.
