A bullet is fired at a target with a velocity 80 m/s and penetrates 50 cm into it. If this bullet were fired into a target 25 cm thick with equal velocity, with what velocity would it emerge, supposing the resistance to be uniform and the same in both the cases?

• A. \[\sqrt{80}m/s\]
• B. \[\frac{40}{\sqrt{2}}m/s\]
• C. \[40m/s\]
• D. \[40\sqrt{2}m/s\]
