Problem 25AAE Theory and Examples Free fall in the fourteenth century In the middle of the fourteenth century, Albert of Saxony (1316–1390) proposed a model of free fall that assumed that the velocity of a falling body was proportional to the distance fallen. It seemed reasonable to think that a body that had fallen 20 ft might be moving twice as fast as a body that had fallen 10 ft. And besides, none of the instruments in use at the time were accurate enough to prove otherwise. Today we can see just how far off Albert of Saxony’s model was by solving the initial value problem implicit in his model. Solve the problem and compare your solution graphically with the equation You will see that it describes a motion that starts too slowly at first and then becomes too fast too soon to be realistic.

Problem 26AAE Theory and Examples Group blood testing During World War II it was necessary to administer blood tests to large numbers of recruits. There are two standard ways to administer a blood test to N people. In method 1, each person is tested separately. In method 2, the blood samples of x people are pooled and tested as one large sample. If the test is negative, this one test is enough for all x people. If the test is positive, then each of the x people is tested separately, requiring a total of x + 1 tests. Using the second method and some probability theory it can be shown that, on the average, the total number of tests y will be With q = 0.99 and N = 1000, find the integer value of x that minimizes y. Also find the integer value of x that maximizes y. (This second result is not important to the real-life situation.)

Problem 35AAE Theory and Examples The best branching angles for blood vessels and pipes When a smaller pipe branches off from a larger one in a flow system, we may want it to run off at an angle that is best from some energy saving point of view. We might require, for instance, that energy loss due to friction be minimized along the section AOB shown in the accompanying figure. In this diagram, B is a given point to be reached by the smaller pipe, A is a point in the larger pipe upstream from B, and O is the point where the branching occurs. A law due to Poiseuille states that the loss of energy due to friction in non-turbulent flow is proportional to the length of the path and inversely proportional to the fourth power of the radius. Thus, the loss along AO is and along OB is where k is a constant, d1 is the length of AO, d2 is the length of OB, R is the radius of the larger pipe, and r is the radius of the smaller pipe. The angle is to be chosen to minimize the sum of these two losses: In our model, we assume that AC = a and BC = bare fixed. Thus we have the relations so that We can express the total loss L as a function of : a. Show that the critical value of for which equals zero is b. If the ratio of the pipe radii is r/R = 5/6, estimate to the nearest degree the optimal branching angle given in part (a).

Problem 2AAE Functions and Derivatives Is it true that a discontinuous function cannot have both an absolute maximum and an absolute minimum value on a closed interval? Give reasons for your answer.

Problem 2PE Extreme Values Does have any local maximum values? Give reasons for your answer.

Problem 2QGY What does it mean for a function to have a local extreme value on its domain? An absolute extreme value? How are local and absolute extreme values related, if at all? Give examples.

Problem 19AAE Limits Evaluate the following limits.

Problem 19PE The Mean Value Theorem Water in a reservoir As a result of a heavy rain, the volume of water in a reservoir increased by 1400 acre-ft in 24 hours. Show that at some instant during that period the reservoir’s volume was increasing at a rate in excess of 225,000 gal/min. (An acre-foot 43,560 ft3is the volume that would cover 1 acre to the depth of 1 ft. A cubic foot holds 7.48 gal.)

Problem 19QGY How can you sometimes handle limits that lead to indeterminate forms ? Give examples.
