Chapter 3, Problem 25P

Use the component method to add the vectors $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$ shown in Figure P3.9. Both vectors have magnitudes of 3.00 m and vector $\stackrel{\to }{A}$ makes an angle of θ = 30.0° with the x axis. Express the resultant $\stackrel{\to }{A}+\stackrel{\to }{B}$ in unit-vector notation.
