Suppose a cup of coffee is 160 degrees right after the coffee is poured. You are only comfortable drinking coffee when it cools to 120 degrees. You check after five minutes, and the coffee is still hot (135 degrees!). When will you be able to first comfortably sip the coffee? Note: The equation for Newton’s law of cooling is ?? = ? (? − ??); its solution is:T(t) = Ts + (T0 – Ts) e^kt. Assume the surrounding temperature is 75 degrees.
