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 the mass and \( v \) is the speed of the object. If both objects have equal mass, the object with the greater kinetic energy must have a greater speed.
