A bullet of $10\ \text{g}$ leaves the barrel of gun with a velocity of $600\ \text{m s}^{-1}$. If the barrel of gun is $50\ \text{cm}$ long and mass of gun is $3\ \text{kg}$, then value of impulse supplied to the gun will be
Answer: (A) $6\ \text{N s}$
The gun receives an impulse equal in size to the bullet's momentum: $0.01\times600=6\ \text{N s}$.
