b. In order to determine the velocity of the center of mass we will allow an arbitrary amount of time to pass, say 2.0
s, and then determine the new position of blockA. Once we have this position we will find the new location of the
center of mass of the two-block system and find the displacement of the center of mass. Then, the velocity of the
center of mass can easily be determined.
