Math 106L Applications: Heating and Mixing I Lecture 13-2 Newton's Law of Cooling Newton formulated the principle that the rate of change of the temperature of an object is proportional to the difference between the object's temperature and the temperature of the surroundings. 1. (a) Suppose that the temperature of an object at time $ t $ is given by $ T(t) $. Denote the surrounding temperature $ T^{*} $, and assume it is constant. Write down a differential equation expressing Newton's Law of Cooling: \[ \frac{d T}{d t}=\underline{K\left(T-T^{*}\right)} \] Note that if the surrounding temperature is greater than the temperature of the object, we expect the temperature of the object to heat, whereas if the surrounding temperature is lower than the temperature of the object, we expect the temperature of the object to $ \mathrm{COO} $. Given that we usually take our constants of proportionality to be positive, does your equation above reflect this? If not, correct it. (b) What is the equilibrium solution to your differential equation? By sketching a slopefield (pick values of $ k $ and $ T^{*} $ if needed), determine if the equilibrium is stable or unstable. (c) Plot two solutions of the equation on your slopefield. One with $ T(0)>T^{*} $, and one with $ T(0)<T^{*} $. What is the behavior of the solutions as $ t \rightarrow \infty $ ? Why does this make sense?

Learning Goal: To find a position vector between two arbitrary points. As shown, two cables connect three points. C is below A by a distance C_z = 1.30 ft and connected to A by a cable 9.95 ft long. Cable AC forms an angle $\beta = 25.0^\circ$ with the positive y axis. B is 9.50 ft above C and the distances $B_x$ and $B_y$ are 7.10 ft and 4.30 ft, respectively. (Figure 1) Part A - Position vector from A to B Using the dimensions in the figure, find the position vector from A to B in component form. Express your answers, separated by commas, to three significant figures. Part B - Unit direction vector for line AB For the position vector found in Part A, find the unit direction vector acting in the same direction. Express your answer in component form. Express your answers, separated by commas, to three significant figures. Part C - Position vector from A to C The length of cable AC is 9.95 ft, and the cable forms the angle $\beta = 25.0^\circ$ with the y axis. Given this information and the dimensions provided in the figure, find the position vector from A to C. Express the position vector in component form. Express your answers, separated by commas, to three significant figures.
