The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take \( \overrightarrow{\mathrm{F}}_{1}=122 \mathrm{~N} \) and \( \overrightarrow{\mathrm{F}}_{2}=77.0 \mathrm{~N} \).) (a) Find the single force that is equivalent to the two forces shown. magnitude \( \mathrm{N} \) direction - - counterclockwise from the \( +x \)-axis (b) Find the force a third person would have to exert on the mule to make the net force equal to zero. magnitude direction - counterclockwise from the \( +x \)-axis
