At a given instant, the position of a plane at \( A \) and a train at \( B \) are measured relative to a radar antenna at \( O \) as shown in (Figure 1). Distances are \( O A=5 \mathrm{~km} \) and \( O B=1 \mathrm{~km} \) Figure Formulate a position vector, directed from \( A \) to \( B \). Enter the components of the vector separated by commas. Express your answer in kilometers to three significe
