Question:
(a) A cup of coffee has temperature 95°C and takes 30 minutes to cool to 61°C in a room with temperature 20°C. Use Newton’s Law of Cooling to show that the temperature of the coffee after t minutes is
T(t) = 20 + 75e–kt
where k ≈ 0.02.
(b) What is the average temperature of the coffee during the first half hour?
