Aplane traveling north at 100.0 km/h through the air gets caught in a 40.0 km/h crosswind blowing west. this turbulence caused a beverage cart to brake free and begin rolling at 20.0 km/h toward the tail of the plane. what is the velocity of the cart relative to the ground? (you do not have to convert these since they are all the same unit)

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.
