The small archerfish (length 20 to 25 cm) lives in brackish waters of Southeast Asia from India
Question:
The archerfish has high accuracy at distances of 1.2 m to 1.5m, and it sometimes makes hits at distances up to 3.5 m. A groove in the roof of its mouth, along with a curled tongue, forms a tube that enables the fish to impart high velocity to the water in its mouth when it suddenly closes its gill flaps. Suppose the archerfish shoots at a target 2.00 m away, at an angle of 30.0o above the horizontal. With what velocity must the water stream be launched if it is not to drop more than 3.00cm vertically on its path to the target?
