Newton's law of cooling states that the rate of change in the temperature T(t) of a body is proportional to the difference between the temperature of the medium M(t) and the dT temperature of the body. That is, = K[M(t) – T(t)], where K is a constant. Let K = 0.03 (min)' and the temperature of the medium be constant, M(t) = 290 kelvins. If the body is dt initially at 359 kelvins, use Euler's method withh = 0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
