A car travels for 10s at a steady speed of 20m/s along a straight road. the traffic lights ahead change to red and the car slows down with a constant deceleration so that it halts after a further 8s.
a. draw a a speed-time graph to represent the car's motion during the 18 seconds described.
b. use the graph to deduce the car's celebration as it slows down.
c. use the graph to deduce how far the car travels during the 18s described.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
