An archer fish spies an insect on a stalk of grass
overhanging the pond, and squirts some water at it to
knock it into the water. The insect is 0.30 m
horizontally from the fish and some distance above it.
The fish spits its water at a speed of 3.0 m/s, at an
angle of 75° above horizontal.
(a) How much time does the insect have to react before
the water hits it?
(b) How far above the fish was the insect?
(c) How fast is the water moving when it hits the insect?

An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. If the fish is to successfully spit at and strike the grasshopper, which is 0.27 m away horizontally and 0.605 m above his mouth, what is the minimum speed at which the archer fish must spit? What angle above the horizontal must he spit? |vi| = ____ m/s θi =______ ° above the...
mAK hericeritaL diff 5. A type of fish hunts by dislodging an unsuspecting insect from its resting place with a stream of water expelled from the fish's mouth. Suppose the fish squirts water with an initial speed of 2.50 m/s at an angle of 20.5" above the horizontal. When the stream of water reaches a beetle on a leaf at a height h above the water's surface, it is moving horizontally. How much time does the beetle have to react?...
