You stand on the seat of a chair and then hop off.
A) During the time you are in flight down to the floor, the Earth moves toward you with what acceleration?
B) The Earth moves toward you through what distance?

Explanation:

A ) When a person is falling under gravity , he goes close to the earth with acceleration 9.8 m /s² . Here we assume that earth is stationary , though it is not . We can also say that earth is moving towards the person with acceleration 9.8 m /s² . The displacement or movement is a relative measurement . So is acceleration .

So the answer to first question is 9.8 m /s²

B ) Displacement of person in this case towards the earth is equal to height of the chair . Here we assume that earth is stationary ,  though earth is not stationary . It is constantly moving around the sun.  Similarly we can also say that earth has moved towards the person by distance equal to height of the chair , if we consider person to be stationary.

answer; /// the above statement is (true);
