Consider the situation in which object X has a speed of 2 m/s and object Y has a speed of 5 m/s after the collision takes place. After the collision, both objects travel in the same direction. Which of the following predictions must be true about how the momentum p of the two-object system and the kinetic energy K of the two-object system change from before the collision to after the collision? K Remains constant Remains constant Remains constant Decreases
