Question

Two bodies of 6 kg and 4 kg masses have their velocity 5 -2+10 and 10 -2+5 respectively. Then the velocity of their centre of mass is

Answer 1

Explanation:

Two bodies of masses =6kg and 4kg

Two bodies of velocity= 5-2+10 and 10-2+5

Then velocity of their centre of mass is 5-2+10×6 and 10-2+5.

=13×6 and13×4

=78 and52.

Then velocity of their centre of mass is 78 and 52.
