Newton's law of cooling says that the temperature of a body changes at a rate proportional to the difference between its temperature and that of the surrounding medium (the ambient temperature), dT dt -k (T – Ta) %3D where T= the temperature of the body (°C), t = time (min), k = the proportionality constant (per minute), and Ta = the ambient temperature (°C). Suppose that a cup of coffee originally has a temperature of 70°C. Use Euler's method to compute the temperature from t = 0 to 20 min using a step size of 2 min if Ta = 20 °C and k = 0.019/min. (Round the final answers to five decimal places.)
