The correct response is: "One object has a greater speed than the other object."
Kinetic energy (KE) is given by the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is mass and \( v \) is speed. Since the two objects have equal mass, the kinetic energy can differ based on their speeds. Therefore, if one object is moving faster than the other, it will have greater kinetic energy.
