A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass $$2$$ m is projected horizontally from the top of a tower of height $$2$$ h, it reaches the ground at a distance $$2x$$ from the foot of the tower. The horizontal velocity of the second body is
