Question: A stone falls down without initial velocity from a height h onto the Earth's surface. The air drag assumed to be negligible, the stone hits

A stone falls down without initial velocity from a height h onto the Earth's surface. The air drag assumed to be negligible, the stone hits the ground with velocity vo = √2gh relative to the Earth. Obtain the same formula in terms of the reference frame “falling” to the Earth with a constant velocity vo.
