One stone is dropped from a tower from rest and simultaneously another stone is projected vertically upwards from the tower with some initial velocity. The graph of distance (s) between the two stones varies with time (t) as (before either stone hits the ground).

Average velocity of a particle moving in a straight line with constant acceleration a and initial velocity u in first t seconds is.
