A=<1.3,2.25> B=<4.1,3.75> just add component by component A+B=<1.3+4.1,2.253.75> <5.4,1.5> For magnitude \[\sqrt{(5.4)^2+(1.5)^2}\] for direction \[tan^{1}(1.5/5.4)\]

let me see what you do

the formula to get the vector is \[vector A= \sqrt{Ax ^{2}+ Ay^2}\] and \[Vector B= \sqrt{Vx^{2} + Vy^{2}\}

oh ,you will add it afterward

just add it? so I came up with vector A=2.6 and vector B=5.56 so vector A + vector B = 2.6 + 5.56=8.16?

I think you are better off adding two vector component by component and then taking mag

I think that part is on how to get the magnitude. right?

magnitude of A+B

yajjnobee Group TitleBest ResponseYou've already chosen the best response.0
yeah so the magnitude is \[\sqrt{(5.4)^2 + (1.5)^2}\]?

will I do the same thing on part c and d?

hey, ahmm, accordingly, when u get the magnitude, the formula for xcomp. is A cos \[\Theta\] right so we need to find the angle before we get the magnitude?

oh , if you are given magnitude and direction , yes

i dunno what to do. what will be my answer on letter b. drivin me crazy.

yajjnobee Group TitleBest ResponseYou've already chosen the best response.0
how can I get the value of xcomponent if the angle is not given. and it's impossible to compute the direction first because it needs the value for both x and y components
