A body of mass 300g kept at rest breaks into two parts due to internal force. One part 200g found to move at speed act of 12 m/s towards north what will be

the velocity of the other part and in which direction it will move.


The body is at rest and force is internal hence the body breaks due to equal force so,
when mass=200 g=0.2 kg
and velocity=12 m/s
Force=mass*velocity=0.2 kg*12 g=2.4 N
equal force on the other part so,
velocity=2.4 N/0.3 kg=8 m/s.
the other part will move in the opposite direction that is south.
