That's disappointing to know that I've learned something wrong. Thank you very much. I really appreciate what you did here.

Nice, thank you very much! We had a whole chapter about vectors and we learned that we were supposed to do it the way I did it, why is it wrong for the velocity vector to be this way ?

These are the velocity vectors and their sum Shouldn't the angle be the same ? Or is it the same problem with the drawing ?

It is in reference to the -x axis. Theta = 180-32= 148 degrees in negative

I realized my mistake, this one should be right ? So our angle is greater than 90 and is negative.

I am sorry for the drawing's quality, it's my first time using this site.It makes sense that the angle relative to the +x axis is negative and it's less than 90. but the angle I get is positive. What possible negative angle I could get ? I tried using sin(theta) = Fy/F sin^-1(theta) =...

I think it was a wild try, makes no sense but I just added the negative sign. What do you propose I should try

In reference to the positive x-axis I suppose. I am just confused now if I am supposed to use the negative angle or not because the net force is under the +x axis

Based on the drawing it should be in the 3rd quadrant. I tried the negative angle and it was wrong.

Homework Statement A 0.35 kg particle moves in an xy plane according to x(t) = - 11 + 1 t - 6 t3 and y(t) = 19 + 3 t - 8 t2, with x and y in meters and t in seconds. At t = 0.7 s, what are (a) the magnitude and (b) the angle (within (-180°, 180°] interval relative to the positive direction of...
