What woudl you expect the motion after the collision to be?

In this question, direction of motion must be given so you can calculate the exact answer. If we accept that both of the subjects are on x axis, we can calculate the common velocity after inelastic collisions. The result is 0,000999 m/Sn. As you see it is very small velocity to observe. So we can see they are stable (at frictional surface) but if you are in laboratory and made up in frictional surface, you can watch their travelling with too small velocity in a long time
