The momentum of a system is conserved
Always
Never
In the absence of an external force on the system
None of the above
Explain conservation of linear momentum by suitable example.
A bullet of mass $40 \,g$ is fired from a gun of mass $10 \,kg$. If velocity of bullet is $400 \,m / s$, then the recoil velocity of the gun will be ..........
The motion of a rocket is based on the principle of conservation of
A bomb is projected with $200\,m/s$ at an angle $60^o$ with horizontal. At the highest point, it explodes into three particles of equal masses. One goes vertically upward with velocity $100\,m/sec,$ second particle goes vertically downward with the same velocity as the first. Then what is the velocity of the third one
Law of conservation of linear momentum is derived by using Newton’s which laws ?
