YET ANOTHER SHADOW PROBLEM

A sidewalk is perpendicular to a long wall, and a man walks along it away from the wall at a rate of 3 feet per second. There is a light on the ground 9 feet (h) from the walk and 14 feet (v) from the wall. When he is 6 feet from the wall, find the following:

(A) How far is the man from his shadow?


(B) How fast is his shadow moving along the wall?


(C) How fast is angle θ changing? (refer to the diagram)




This is an ariel view!
