Question

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 a speed of 2.20 m/s at an angle of 48.0 ∘ above the horizontal, and aims for a beetle on a leaf 2.80 cm above the water's surface.

What is the greatest horizontal distance from which the archerfish can hit the beetle? (answer in cm). I tried 2.67 for this and got it wrong.

How much time does the beetle have to react in this case? (answer in s)
