Asked by Antonio
Upon spotting an insect on a twig overhanging water, an archer fish squirts water drops at the
insect to knock it into the water. Although the insect is at distance d from the fish along a
straight-line path at angle $ (as in the figure here), a drop must be launched at a different
angle if its parabolic path is to intersect the insect. If $ = 32.0° and d = 0.900 m, what is required for the drop to be at the top of the parabolic path when it reaches the insect?
