Arecord of travel along a straight path is as follows:
1. start from rest with constant acceleration of 2.04 m/s2 for 11.0 s.
2. maintain a constant velocity for the next 2.85 min.
3. apply a constant negative acceleration of −9.73 m/s2 for 2.31 s.
(a) what was the total displacement for the trip?
(b) what were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?
(c)complete trip:

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.
