Solve the all part of given question:
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 2.10 m/s at an angle of 52 degrees above the horizontal, and aims for a beetle on a leaf 3.50 cm above the water's surface.
Part A: At what horizontal distance from the beetle should the archerfish fire if it is to hit its target in the least time?
Part B: How much time will the beetle have to react?
I need help to determine how much time the beetle will have to react.
