Neither the kinetic energy nor the momentum of the system is conserved. B. The momentum of the system is conserved, while kinetic energy is not conserved. C. The kinetic energy of the system is conserved, while momentum is not conserved. D. Both the kinetic energy and the momentum of the system are conserved.
