The correct description of the football's motion, assuming no air resistance, is:
In the vertical direction, it moves up quickly, slows down, reverses direction, then speeds up until it hits the ground. In the horizontal direction, it moves at the same speed.
In this scenario, the vertical motion is influenced by gravity, causing the ball to ascend until it reaches its peak height, at which point it reverses direction and descends, accelerating as it falls. The horizontal motion remains constant because, in the absence of air resistance, there are no horizontal forces acting on the football.
