1.	Two particle which are initially at rest, move towards each other under the action of their internal alteration. If there speeds are v and 2v at any instant, then the speed of centre of mass of the system will be……….
Answer» `2V` ZERO `1.5v` `v` Solution :Hence no external force acting on a system of particle and initially its centre of MASS is at rest will be remain at rest in FINAL position and the speed of centre of mass is zero.
