Question

Consider two vectors ~A and ~B and their resultant ~A +~B . The magnitudes of the vectors~A and ~B are, respectively, 14.8 and 5.1 and they act at 140 degrees to each other. Find the magnitude of the resultant vector~A+ ~B.

Answer 1

Dont you know this simple question simply put in the equation

Answer 2

First break up the vectors into their x and y components using trigonometry. Add the x and y components to each other, then use trigonometry and the Pythagorean theorem to find the magnitude and direction of the resultant vector.
