A box with weight $40\,\text{N}$ is moved across level ground through a distance of $2.4\,\text{m}$ by a horizontal force of $20\,\text{N}$. It is then raised vertically at constant velocity by a height of $1.6\,\text{m}$ using a vertical force. What is the total work done on the box by these two forces?
- A$80\,\text{J}$
- B$110\,\text{J}$
- C$120\,\text{J}$
- D$160\,\text{J}$
