MOTION LOAD AND THE ARCHER FISH. Archers are tropical fish that hunt by shooting drops of water from their tops onto insects to return them to the water, where the fish can eat them. A 65 g fish at rest just above the surface of the water can eject a 0.30 g drop of water in a short burst of 5.0 ms. High-velocity measurements show that the water has a speed of 2.5 m/s just after the archer expels it. What is the momentum of a drop of water immediately after it leaves the fish's mouth? What is the average force that the fish exerts on the drop of water? The fish shoots the water droplet at an insect that is moving on the surface of the water, so just before it hits the insect, the droplet is still moving with the speed it left the fish's mouth. on impact the drop sticks to the insect and the speed of the insect and the water just after the impact was measured to be 2 m/s. What is the mass of the insect?
