A hammer that has $10\,\text{J}$ of kinetic energy strikes a nail and drives it $5.0\,\text{mm}$ into a plank. After the collision, both the hammer and the nail are brought to rest. What is the average force acting on the nail as it moves through the $5.0\,\text{mm}$?
- A$0.050\,\text{N}$
- B$2.0\,\text{N}$
- C$50\,\text{N}$
- D$2000\,\text{N}$
