An onject is thrown vertically upward with some speed. It crosses ` 2` points ` p,q` whith are separated by (h) metre. If (t) is the time between (p) and highest point and coming back and ` t_(q)` is the time between `q` and highest point and coming back, relate acceleration due to gravity `t_(p),t_(q) and h`.

An object is thrown vertically upward with some speed. It crosses 2 points p,q which are separated by (h) metre. If t_(p) is the time between p and highest point and coming back and t_(q) is the time between q and highest point and coming back, relate acceleration due to gravity t_(p),t_(q) and h .

A particle is thrown vertically upwards from the surface of the earth. Let T_(P) be the time taken by the particle to travel from a point P above the earth to its highest point and back to the point P. Similarly, let T_(Q) be the time taken by the particle to travel from another point Q above the earth to its highest point and back to the same in terms of T_(P), T_(Q) and H, is :-
