A body is thrown with the velocity u=12.0ms^(-1) at an angle of alpha=45^(@) to the horizon. It touches the ground at the distance s from the point where it was thrown. From what height h should stone be thrown in a horizontal direction, with the same initial velocity u so that it falls at the same spot ?
