- When the human body is at rest, the heart pumps 4.6 L of blood into the aorta every minute. During some exceptional exertion, such as playing sports, the amount of blood delivered to the aorta increases to 25 L every minute. If the area of the opening of the aorta is A = 0.81 cm2 What is the average velocity of blood as it enters the aorta in each of these cases?You step onto a hot beach with your bare feet.

- The trap-jaw ant, found throughout tropical South America, catches its prey by very rapidly closing its mandibles around its victim. (Figure 1) shows the speed of one of its mandible jaws versus time in microseconds. What is the magnitude of the maximum acceleration of the ant's mandible? The mass of a trap-jaw ant's mandible has been estimated to be about 1.1×10−7kg1.1×10−7kg. Estimate the maximum force exerted by one mandible.A caterpillar's speed decreases from 0.50cm/s to 0.25cm/s at a rate of -0.04cm/s2 as it climbs a leaf.
