Question

vector A is 5.5cm and points 60°above the positive x-axis. Vector B is 6.5cm and points along thr negative x-axis. Calculate the magnitude and direction of the resultant of these two vectors.

Answer 1

Vx = 5.5 cos 60 - 6.5
Vy = 5.5 sin 60

|V| = sqrt (Vx^2 + Vy^2)

tan theta = Vy/Vx
note in quadrant 3 (draw it)

Answer 2

I mean quadrant 2, negative x, positive y
