Lurking alligators. An alligator waits for prey byfloating with only the top of its head exposed, so that the preycannot easily see it. One way it can adjust the extent of sinkingis by controlling the size of its lungs. Another way may be byswallowing stones (gastrolithes) that then reside in the stomach. Figure 14-41 shows a highly simplified model (a ''rhombohedrongater'') of mass 130 kg that roams with its head partiallyexposed.The top head surface has area 0.20 m2. If thealligator were to swallow stones with a total mass of 1.0% of itsbody mass (a typical amount), how far (in mm) would it sink?
somone please help me step-by-step with plugging in numbers into appropriate equations...
