The first document describes a problem where a body is acted on by a force that varies inversely with the square of the distance from a fixed point. The path formed will be a parabola. The second document describes a body that starts from rest and moves with constant acceleration. The ratio of the distance covered in the fifth second to that covered in 5 total seconds is 9/25.
