A ball is thrown from the top of a tower in vertically upward direction. Velocity at a point h m below the point of projection is twice of the velocity at a point h m above the point of projection. Find the maximum height reached by the ball above the top of tower.

A ball is thrown vertically up with a certain velocity from the top of a tower of height 40m. At 4.5m above the top of the tower its speed is exactly half of that it will have at 4.5m below the top of the tower. The maximum height reached by the ball aboe the ground is 47.5K m. Find K.
