Suppose that you are a CSI and you are called to a crime scene at 12:00 noon and find a dead body in a walk-in that is a constant 40¨H. The initial temperature is 85¡ã and after 20 minutes. The body¡¯s temperature is 84¡ã. Using Newton¡¯s Law of cooling u(t) = T +(u0 ¨C T)ek . t , k< 0, T temperature of the surrounding medium, u0 is the initial temperatures of the object. If we assume that 98.6 ¨H when was the time of death?
