Question
Two manned satellites approach one another at a relative speed of 0.250 m/s, intending to dock. The first has a mass of $4.00 \times 10^3 \textrm{ kg}$, and the second a mass of $7.50 \times 10^3 \textrm{ kg}$ . If the two satellites collide elastically rather than dock, what is their final relative velocity?

$-0.250 \textrm{ m/s}$
