The archerfish hunts by dislodging an unsuspecting insect from its resting place with a stream of water expelled from the fish’s
mouth. Suppose the archerfish squirts water with an initial speed of 2.30 m/s at an angle of 19.5° above the horizontal. When the stream of water reaches a beetle on a leaf at height h above the water’s surface it is moving horizontally. (a) How much time does the beetle have to react? (b) What is the height ℎ of the beetle? (c) What is the horizontal distance d between the fish and the beetle when the water is launched?
