A veterinarian wants to determine temperature of a sick horse. The readings on the thermometer follow Newton\'s Law. At the time of insertion the thermometer reads 82 degree farenheit. After 3 minutes the reading is 90 degree farenheit, and 3 minutes later 94 degree farenheit. A sudden convulsion destroys the thermometer before a final reading can be obtained. What is the horse\'s temperature? Solution newton s law = dT /dt = k(T-To) T / t = k (T-90) T2 /t2 = k(T-94 ) now 8/3 = k(T-90)..........1 4/3 = k(T-94)....................2 divide 1/ 2 we get 2 = (T-90) /(T-94) here we get, T = 98 The horse\'s temperature = 98 degree farenheit.
