The archerfish is a type of fish well known for its ability to catch resting insects by spitting a jet of water at them. this spitting ability is enabled by the presence of a groove in the roof of the mouth of the archerfish. the groove forms a long, narrow tube when the fish places its tongue against it and propels drops of water along the tube by compressing its gill covers. when an archerfish is hunting, its body shape allows it to swim very close to the water surface and look upward without creating a disturbance. the fish can then bring the tip of its mouth close to the surface and shoot the drops of water at the insects resting on overhead vegetation or floating on the water surface. part a: at what speed v should an archerfish spit the water to shoot down a floating insect located at a distance 0.800 m from the fish? assume that the fish is located very close to the surface of the pond and spits the water at an angle 60 degrees above the water surface. part b: now assume that the insect, instead of floating on the surface, is resting on a leaf above the water surface at a horizontal distance 0.600 m away from the fish. the archerfish successfully shoots down the resting insect by spitting water drops at the same angle 60 degrees above the surface and with the same initial speed v as before. at what height h above the surface was the insect?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
