Best ResponseYou've already chosen the best response.0A=<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 \[tan^{1}(1.5/5.4)\]

Best ResponseYou've already chosen the best response.0the formula to get the vector is \[vector A= \sqrt{Ax ^{2}+ Ay^2}\] and \[Vector B= \sqrt{Vx^{2} + Vy^{2}\}

Best ResponseYou've already chosen the best response.0just 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?

Best ResponseYou've already chosen the best response.0I think you are better off adding two vector component by component and then taking mag

Best ResponseYou've already chosen the best response.0I think that part is on how to get the magnitude. right?

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

Best ResponseYou've already chosen the best response.0will I do the same thing on part c and d?

Best ResponseYou've already chosen the best response.0hey, 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?

Best ResponseYou've already chosen the best response.0oh , if you are given magnitude and direction , yes

Best ResponseYou've already chosen the best response.0i dunno what to do. what will be my answer on letter b. drivin me crazy.

Best ResponseYou've already chosen the best response.0how 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
