The correct response is: One object has a greater speed than the other object.
In classical physics, the kinetic energy (KE) of an object is given by the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass and \( v \) is the velocity (speed) of the object. If both objects have equal masses, the one with the greater speed will have greater kinetic energy.
