Ccording to newton's law of cooling, if a body with temperature upper t 1t1 is placed in surroundings with temperature upper t 0t0, different from that of upper t 1t1, the body will either cool or warm to temperature t(t) after t minutes, wheret(t)equals=upper t 0t0plus+(upper t 1t1minus−upper t 0t0)e superscript negative kte−kt. a cup of coffee with temperature 160degrees°f is placed in a freezer with temperature 0degrees°f. after 15 minutes, the temperature of the coffee is 47degrees°f. use newton's law of cooling to find the coffee's temperature after 20 minutes.
