The correct response to the question is:
**One object has a greater speed than the other object.**
Kinetic energy depends on both the mass and the speed (velocity) of an object, and is calculated using the formula \( KE = \frac{1}{2} mv^2 \). Since the masses are equal, a difference in speed would result in a difference in kinetic energy.
**One object has a greater speed than the other object.**
