Using Newton's Law of Cooling, I have to predict the time of death of a person.
H-R = Be^-kt is the relationship between the temperature of the body (H) and the constant room temperature (R), t is the time in hours since the body expired and k and B are the constants. Using that equation I have to determine the time of death.
When the murder is committed, the body, originally at 37'C, cools according to Newton's Law of Cooling, if the body is found at 9:30am the temperature of the body is 35'C and that temperature of the body is 30'C at 4:00pm. Assuming that the temperature of the surrounding air is a constant 20'C.
I know how to solve simpler exponential models, but I'm confused how to do this one.
