Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the rod. Assuming that her rod to the fly) is taut, how much string does she have out(see fig)? If she pulls in the string at the rate of 5 cm per second, what will be the heriozontal distance of the fly from her after 12 seconds.
