Two objects of the same mass travel in the same direction along a horizontal surface. Object X has a
speed of 5 m and object Y has a speed of 2 m, as shown in the figure. After a period of time, object X
collides with object Y.
Consider the situation in which the objects collide but do not stick together. Which of the following
predictions is true about the center of mass of the two-object system immediately after the collision?
The center of mass does not move.
The velocity of the center of mass does not change.
The velocity of the center of mass decreases in speed.
The velocity of the center of mass increases in speed.
