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