Question

Two bodies of different masses 2kg and 4kg are moving with velocities 2m/s and 10m/s towards each other due to mutual gravitational attraction. Then the velocity of the centre of mass is

Easy

Solution

$v_{cm} = \frac{m_{1} v_{1} + m_{2} v_{2}}{m_{1} + m_{2}}$ ;Internal force does not change the position of centre of mass
