A measurement of free-fall acceleration,g, was made by throwing a glass ball straight up in an evacuated tube and letting it return. Let ΔTl be time interval between two passages of ball across a certain lower level, ΔTu the time interval between the two passes across an upper level, and H the distance between the two levels.
Show that g=(8H)/(ΔTl^2-ΔTu^2)
I have no idea how to begin this proof.
I've attempted to draw a picture that is attached.
