According to newton's law of cooling, if a body with temperature upper t 1 is placed in surroundings with temperature upper t 0, different from that of upper t 1, the body will either cool or warm to temperature t(t) after t minutes, where t(t)equalsupper t 0plus(upper t 1minusupper t 0)e superscript negative kt. a cup of coffee with temperature 140degreesf is placed in a freezer with temperature 0degreesf. after 15 minutes, the temperature of the coffee is 41degreesf. use newton's law of cooling to find the coffee's temperature after 20 minutes.
