A car travels on a level road. Its starting kinetic energy is $280\,\text{kJ}$. A constant resistive force of $200\,\text{N}$ acts on the car. No other horizontal forces act on the car. What is the kinetic energy of the car after it has moved a distance of $300\,\text{m}$?

  • A$60\,\text{kJ}$
  • B$80\,\text{kJ}$
  • C$220\,\text{kJ}$
  • D$340\,\text{kJ}$
