Question

Two particles of masses 1 kg and 3 kg move towards each other under their mutual force of attraction no other force acts on them when the relative velocity of approach of the two particles is 2m/s their centre of mass has a velocity of 0.5 m/s when the relative velocity of approach becomes 3 m/s the velocity of the centre of mass is

Answer 1

Explanation:

Two particles of masses 1 kg and 3 kg move towards each other under their mutual force of attraction no other force acts on them when the relative velocity of approach of the two particles is 2m/s their centre of mass has a velocity of 0.5 m/s when the relative velocity of approach becomes 3 m/s the velocity of the centre of mass is
