The correct response is:

One object has a greater speed than the other object.

Kinetic energy is given by the formula \( KE = \frac{1}{2} mv^2 \), where \( m \) is mass and \( v \) is speed. Since both objects have equal masses, if one object has a greater speed, it will have a greater kinetic energy.
