1. LAW OF COOLING PROBLEM!HELP PLEASE! :)
At 1:00pm, Sally puts into a refrigerator a can of soda that has been sitting of temperature 70degF. The temperature in the refrigerator is 40degF. fifteen minutes later 1:15pm, the temperature of the soda has fallen to 60degF. At some time later, Sally removes the soda form the refrigerator to the room, where at 2:00pm, the temperature of the soda is 60degF. At what time did Sally remove the soda from the refrigerator?
2.dT/dt= -k(Tsoda-Tref)
3. Tsoda=Tref + e^-kt(Tsoda-Tref)
at 1:15pm
60= 40 + e^-k(15)(70-40)
k= .027031
i don't know what to do next.. help please..
