A 10000-kg load sits on the flatbed of a 20000-kg truck moving at 12.0 m/s. Assume that the load is not tied down to the truck, but has a coefficient of static friction of 0.500 and a coefficient of kinetic friction of 0.400 with the flatbed of the truck. If the truck needs to stop in 10.0 m with constant acceleration, what is the force of friction between the load and the truck when the brake is first applied

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.
