1. ## Cooling/temperature Problem

A thermometer is taken from a room where the temperature is 85 degrees and carried outdoors. A minute later the thermometer reads 65.5 degrees and another minute it reads 51.85 degrees. How cold is it outside?

t(0) = 85
t(1) = 65.5
t(2) = 51.85

How do I solve to find the temperature outside?

2. The following formula for the cooling of an object is derived from Newtons Law of Cooling

$\displaystyle T- T_s = Ae^{-kt}$

T is the temperature of the object
$\displaystyle T_s$ is the ambient temperature
k is a cooling(or insulation) factor
A is the temperature difference at t=0

There are three unknowns + you have data for three equations = probably solvable...
