Answer:
6.8 mm
Explanation:
We are given that
Mass of block,m=10 kg
Mass of bullet,
1 kg=1000 g
Total mass of system,M=
Speed of bullet,u=300 m/s
By law of conservation of momentum
According to law of conservation of energy
Change in kinetic energy of system=Change in potential energy of system
Where 
1m=100 cm
Distance traveled by block=
1cm=10 mm
