2. Two gliders are on a frictionless, level air track.
Initially. glider A moves toward the right and
glider B is at rest. After the collision, glider A has
reversed direction and moves toward the left. The
combined system of both gliders is denoted as

The mass of glider A is one fourth the mass of
glider B.

Draw an arrow to represent the direction of the initial velocity (before the
collision) of the center of mass of system C. If the initial velocity of the
center of mass is zero, state that explicitly. Explain.

Is the magnitude of the change in velocity vector for glider A greater than, less than, or
equal to the magnitude of the change in velocity vector for glider B? Explain.

d. Consider the following incorrect statement:
"Glider B will move to the right after this collision, but it would move faster if glider A
were to come to a stop, giving glider B all its momentum."
