## Homework Statement

Could someone please read through my work to make sure I have worked this out correctly, please see the images below for my working out.

A space vehicle travelling at a velocity of 6000km/h separates by detonation of explosive bolts, into two sections of mass 1200 kg and 300 kg. The two parts continue moving in the same direction with the lighter section moving at 6200km/h. Making use of the principle of conservation of momentum, determine the velocity of the heavier section after separation

Which problem do you need help on? The problem in post #1 makes little sense. If the ejected mass has more momentum than before, then the space vehicle will have less momentum than before. Usually, this type of maneuver is intended to boost the momentum of the space vehicle. Are you sure that the velocities are correct and relative to the lab frame?
