In Winter an aluminum beam was brought from the outside cold into a machine shop where the temperature was held at 65◦. After 15 minutes, the beam warmed to 35◦ and after another 15 minutes it was 45◦. Assuming the beam obeys Newton’s Law of Cooling, what was the beam’s initial temperature? Do NOT approximate any values.
