Question

2. (20 points) According to Newton's law of cooling/warming, the rate at which the temperature of a body changes is proportional to the difference between the temperature of the body and the temperature of the surrounding medium, the so-called ambient temperature. If T (t) represents the temperature of a body at time t, Tm the temperature of the surrounding medium, and the rate at which the temperature of the body changes, then Newton's law of cooling/warming translates into the mathematical statement drdtIm
