  1. For part (f), why not include the energy needed for the car to travel 1km in addition to the energy transferred to the air (i.e. why not add your answer of 50kJ to 500kJ from part (d) ) ?

  2. Hello, I’m quite confused about question(c), should total energy include energy to restart the car ? In that case , answer will be doubled: mv^2d/s
