Vector A is 2.80 cm long and is 60.0 o above the x-axis in the first quadrant.

Question:

Vector A is 2.80 cm long and is 60.0^oabove the x-axis in the first quadrant. Vector is 1.90 cm long and is below the x-axis in the fourth quadrant (Fig. E1.39). Use components to find the magnitude and direction of

(a) A + B;

(b) A €“ B;

(c) B €“ A. In each case, sketch the vector addition or subtraction and show that your numerical answers are in qualitative agreement with your sketch.
