Vector a s is 2.80 cm long and is 60.0° above the x-axis in the first quadrant. vector b s is 1.90 cm long and is 60.0° below the x-axis in the fourth quadrant (fig. e1.35). use components to find the magnitude and direction of (a) a s + b s ; (b) a s − b s ; (c) b s − a s . in each case, sketch the vector addition or subtraction and show that your numerical answers are in qualitative agreement with your sketch.
