  • a)
    The kinetic energy as measured from centre of mass frame is least 
  • b)
    The system always retains at least Kcm amount of kinetic energy as measured from ground frame irrespective of any kind of internal changes in the system. 
  • c)
    The system always retains at least K0–Kcm amount of kinetic energy as measured from ground frame irrespective of any kind of internal change in the system. 
  • d)
    Only the portion of energy Kcm can be transformed from one form to another due to internal changes in the system.
Correct answer is option 'A,C,D'. Can you explain this answer?

It can be shown that
 
where M is the total mass of the system and Vcm is velocity of centre of mass with respect to ground.
Due to internal changes Kcm can change but Vcm will remain same. Hence only Kcm portion of kinetic energy can be transformed to some other from of energy.
The correct answers are: The kinetic energy as measured from centre of mass frame is least, Only the portion of energy Kcm can be transformed from one form to another due to internal changes in the system., The system always retains at least K0Kcm amount of kinetic energy as measured from ground frame irrespective of any kind of internal change in the system.
