    |dw:1327785538641:dw|Break up each vector into components:\[\overrightarrow{V}=\overrightarrow{V_P}+\overrightarrow{V_A}=<260,0>+<100\cos(30^{\circ}),100\sin(30^{\circ})>\]Add the vectors together, the magnitude of the resulting vector will be your total speed\[|\overrightarrow{V}|=\sqrt{({\text{x-component})^2+(\text{y-component})^2}}\]
