(13%) Problem 3: While watching the clouds pass by, you notice a European swallow flying horizontally at a height of h = 22.65 m. When the swallow is directly overhead, it drops an m = 11.7 kg coconut. Refer to the diagram. From your ornithological studies, you know that the air- speed of this particular species of swallow, while carrying such a load, is vo=7.88 m/s. Neglect air resistance.

Problem 10: While watching the clouds pass by, you notice a European swallow flying horizontally at a height h = 21.9 m above you. When the swallow is directly overhead, it drops an m = 10.7 kg coconut. From your ornithological studies, you know that the air-speed of this particular species of swallow while carrying such a load is vo = 7.73 m/s. In this problem you may neglect air friction. Refer to the diagram. Assume the origin of the coordinate system there is at your head. h

You are watching a National Geographic Special on television. One segment of program is about archer fish, which inhabit streams in southeast Asia. This actually "shoots" water at insects to knock them into the water so it can eat th The commentator states that the archer fish keeps its mouth at the surface of stream and squirts a jet of water from its mouth at 13 feet/second. You watch archer fish shoot a juicy moth off a leaf into the water. You estimate that the was about 2.5 feet above a stream. You wonder at what minimum angle from horizontal the water can be ejected from the fish's mouth to hit the moth.

Problem 10: While watching the clouds pass by, you notice a European swallow flying horizontally at a height of h = 21.95 m. When the swallow is directly overhead, it drops an m = 10.5 kg coconut. Refer to the diagram. From your ornithological studies, you know that the air-speed of this particular species of swallow, while carrying such a load, is vo = 6.93 m/s. Neglect air resistance.
