A hammer carrying $10\,\text{J}$ of kinetic energy strikes a nail and drives it $5.0\,\text{mm}$ into a plank. After the impact, both the hammer and the nail are at rest. What is the approximate average force acting on the nail during the $5.0\,\text{mm}$ penetration?
- A$0.050\,\text{N}$
- B$2.0\,\text{N}$
- C$50\,\text{N}$
- D$2000\,\text{N}$
