The figure below shows a track with a small marble starting from rest at a height h, above
the point where the marble leaves the track. When the marble leaves the track, it leaves at
an angle e with the horizontal and at a height h, above the ground. It then flies through the
air until it hits the ground at a distance D to the right from the bottom of the table.
