This problem I know has to dowith similar triangles which I have tried to set up based on mylecture notes, but it was a completely different problem withcylinders and cones, so I'm not sure how to set this up?
A street light is at the topof a 14 ft tall pole. A woman 6 ft tall walks away from the polewith a speed of 4 ft/sec along a straight path. How fast is the tipof her shadow moving when she is 30 ft from the base of thepole?
Note: You should draw apicture of a right triangle with the vertical side representing thepole, and the other end of the hypotenuse representing the tip ofthe woman's shadow. Where does the woman fit into this picture?Label her position as a variable, and label the tip of her shadowas another variable. You might like to use similar triangles tofind a relationship between these two variables.
