Object X is at a small height h above the surface of the Earth and then falls from rest to the surface. The speed of object X when it reaches the surface of the Earth is v_X. Object Y is at a small height 2h above the surface of the Moon and then falls from rest to the surface. The speed of object Y when it reaches the surface of the Moon is v_Y. The acceleration of free fall on the Moon is 1.6 m s^-2. The drag force acting on both objects is negligible. What is the ratio v_X/v_Y?
