Serway & Jewett — Vectors: Problem 9

The displacement vectors \(\vec{A}\) and \(\vec{B}\) shown in Figure P3.9 both have magnitudes of \(3.00\text{ m}\). The direction of vector \(\vec{A}\) is \(\theta = 30.0^\circ\). Find graphically (a) \(\vec{A} + \vec{B}\), (b) \(\vec{A} - \vec{B}\), (c) \(\vec{B} - \vec{A}\), and (d) \(\vec{A} - 2\vec{B}\). (Report all angles counterclockwise from the positive \(x\) axis.)
