Chapter 1, Problem 48P

Use the component method to add the vectors $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$ shown in Figure P1.34. Express the resultant $\stackrel{\to }{A}+\stackrel{\to }{B}$ in unit-vector notation.

34. The displacement vectors $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$ shown in Figure P1.34 have magnitudes of 3.00 m. The direction of vector $\stackrel{\to }{A}$ is θ = 30.0°. Find graphically (a) $\stackrel{\to }{A}+\stackrel{\to }{B}$, (b) $\stackrel{\to }{A}-\stackrel{\to }{B}$, (c) $\stackrel{\to }{B}-\stackrel{\to }{A}$, and (d) $\stackrel{\to }{A}-2\stackrel{\to }{B}$. (Report all angles counterclockwise from the positive x axis.)
