College Trig Merry-Go-Round Extended Problem, please help?

[duskowl45]

Illuminated by the rays of the setting sun, Allie rides alone on a merry-go-round, casting a moving shadow on the wall. The merry-go-round is turning 40 degrees per second. As the top view shows, Allie is 20 feet from the center of the merry-go-round, and the sun's rays are perpendicular to the wall. Let N be the point on the wall that is closest to the merry-go-round. What is the approximate speed (feet per second) of Allie's shadow when it passes N? What is the approximate speed of this shadow when it is 10 feet from N?

Where is the sketch? Where is the top view?
