Object X is at a small height 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 .
Object Y is at a small height 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 .
The acceleration of free fall on the Moon is 1.6 m s.
The drag force acting on both objects is negligible.
What is the ratio ?
