According to newton's law of cooling, if a body with temperature t 1 is placed in surroundings with temperature t 0, different from that of t 1, the body will either cool or warm to temperature t(t) after t minutes, where: t(t) = t 0 + (t 1 - t 0)e kt and k is a constant. a cup of coffee with temperature 140°f is placed in a freezer with temperature 0°f. the constant k ≈ -0.0815. use newton's law of cooling to find the coffee's temperature, to the nearest degree fahrenheit, after 15 minutes. the temperature is about a0degrees fahrenheit.
