A student is conducting experiments with gliders on a horizontal, frictionless track. In trial 1 of an
experiment, a glider moves with speed V, and collides elastically with another glider that is initially at
rest. In trial 2, the setup is identical except that the gliders stick together during the collision. How
does the speed of the two-glider system's center of mass change, if at all, during the collision in
each trial?
