ANSWER:
Solution 10E
Introduction
We will draw a figure of the situation containing all the forces, then we will identify each forces and what are the angles with the displacement, then we will calculate the total work done on the box.
Step 1
The work done by a force is given by
Where is the force is the displacement and is the angle between force and displacement.
