How is a falling meteorite the "time -reversal" of a fired object?
(1) An object is fired vertically upward from the Earth with an initial speed that is less than the escape speed. (2) A meteorite falls towards the Earth; at a certain height, the meteorite is at rest with respect to the Earth. Question: how is (2) the "time reversal" of (1)? Why can we use the same equation for both questions by reversing Vf to Vi? Any help will be appreciated. Thank you.
It isn't. The effects of atmosphere aren't symmetric. The meteorite is never at rest with respect to earth until it lands. If you could ignore the atmosphere, each is an object with a specific position and velocity, acted on by earth's gravitational field.
