OPTIONAL: 5.0 Exercise 4.3 Note : Equation (245) is d( ! V) dt = w i " w Equation (246) is dT dt = w i ! V T i " T ( ) + Q V ! C Eq. (246) has a typo in the textbook; use the equation given above instead. Hint : Applepolsher obtained the wrong answer because he did not notice that = V f (show that this indeed the mistake he made)....
