A chaser spacecraft has an initial position in the HCW reference frame of Δr₀ [2, 3, 4] du, where distance units (du) are sufficiently small for the HCW assumptions to hold, and time units (tu) have been chosen such that n = 1 rad/tu. Write an initial relative velocity vector Δv₀ that has only a single non-zero component and yields a bounded HCW solution
