Question

prove that motion of a system of particles is independent of mutual force​

Answer 1

Answer:

Show p=p i′ +m i V

Show p=p i′ +m i Vwhere p i is the momentum of the ith particle (of mass m i ) and p i′

i′ =m i v i′

Note v i′ is the velocity of the ith particle relative to the centre of mass.

Note v i′ is the velocity of the ith particle relative to the centre of mass. Also, prove using the definition of the center of mass ∑p i′ =0
