At the same instant, ball A is dropped from top of a building of height h and ball b Is projected vertically upwards from the ground with velocity u. The ratio of velocity of A to the velocity of B at the point of collision is same as the ratio of height of this point from the top of the building to the height from the ground . Find the height of the point of collision above the ground.
