Answer :
Given,
Force is F=3.5 N
The mass is m=8g=0.008 kg
To find
The acceleration
Explanation
We know acceleration is force per unit mass
Thus,
[tex]\begin{gathered} a=\frac{F}{m} \\ \Rightarrow a=\frac{3.5}{0.008}=437.5\text{ m/s}^2 \end{gathered}[/tex]Conclusion
The bullets acceleration is
[tex]\frac{437.5m}{s^2}[/tex]
