Afriend asks you how much pressure is in your car tires. you know that the tire manufacturer recommends 30 psi, but it's been a while since you've checked. you can't find a tire gauge in the car, but you do find the owner's manual and a ruler. fortunately, you've just finished taking physics, so you tell your friend, "i don't know, but i can figure it out." from the owner's manual you find that the car's mass is 1100 kg . it seems reasonable to assume that each tire supports one-fourth of the weight. with the ruler you find that the tires are 14 cm wide and the flattened segment of the tire in contact with the road is 13 cm long.

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 temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
