The appropriate answer is ' The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.

Over the first 16.4 m, the person performs
<em>W</em> = (60.0 N) (16.4 m) = 984 J
of work.
Over the remaining 6.88 m, they perform a varying amount of work according to
<em>F(x)</em> ≈ 60.0 N + (-8.72 N/m) <em>x</em>
where <em>x</em> is in meters. (-8.72 is the slope of the line segment connecting the points (0, 60.0) and (6.88, 0).) The work done over this interval can be obtained by integrating <em>F(x)</em> over the interval [0, 6.88 m] :
<em>W</em> = ∫₀⁶˙⁸⁸ <em>F(x)</em> d<em>x</em> ≈ 206.4 J
(Alternatively, you can plot <em>F(x)</em> and see that it's a triangle with base 6.88 m and height 60.0 N, so the work done is the same, 1/2 (6.88 m) (60.0 N) = 206.4 J.)
So the total work performed by the person on the box is
984 J + 206.4 J = 1190.4 J ≈ 1190 J
