Me i am stuck, frustrated, and dont even know how to start this problem ahhsrfhrerhyt
a car is traveling at a constant velocity of 19 m/s when the driver puts on the brakes to accelerate it at -1.4 m/s2 until stopped. how long (in s) did it take the car to stop?

give the answer with two significant digits and without the unit. your answer should be a number only.

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.
