person pushes a box up an incline with constant force, and after calculating how much work they did on the box summed with how much work gravity did on the box they find a non-zero positive result, i.e. ?person>Wgravity. What are two explanations of where the “extra” work done by the person on the box went?

7. A person pushes a box up an incline with constant force, and after calculating how much work they did on the box summed with how much work gravity did on the box they find a non-zero positive result, i.e. ?person>Wgravity. What are two explanations of where the “extra” work done by the person on the box went?
Expert Solution
Step 1
Given work done by the person is greater than the work done by gravity.
When we move a body on an inclined plane we face two forces.
- One gravitational force and
- Second frictional force
Therefore we have to to spend some work against the gravity and some work against the frictional force.
