2D vector magnitude:

$\overline{)\mathbf{\left|}\stackrel{\mathbf{\rightharpoonup}}{\mathit{A}}\mathbf{\right|}{\mathbf{=}}\sqrt{{{\mathit{A}}_{\mathit{x}}}^{\mathbf{2}}\mathbf{+}{{\mathit{A}}_{\mathit{y}}}^{\mathbf{2}}}}$

If F = (-2.8, 7.2), it means that:

F = (-2.8,7.2), where all components are in newtons. What is the magnitude (in newtons) of F? (Reminder: NEVER include units with ANY submission to a numerical question.)
