Mass of station is 3.8X106
Suppose once again that the space station begins at rest, not
rotating. This time, instead of using rocket engines attached to
the spherical end modules, we will have small probes periodically
launched from two points on the rod-shaped part of the station as
shown. The probes will launch in pairs in opposite directions, each
individual probe of identical mass 1287 kg and launched at a speed
of 15900 m/s with respect to the space station....
