You are walking across campus when you see a colorful
piece of paper of mass **m = 0.20 kg** flying through the air.
As the paper enters the science quad, it is moving
North at **v = 4 m/s**.

As the paper goes across the quad, the wind continues to blow it, pushing it through the air. But the force and direction of the wind change as the paper flies.

- How much work does the wind do on the paper as it moves across the quad?
- In this situation, the force of the wind can be expressed
as a quadratic function of position, like so:
Fill in the appropriate values for

**A**and**B**and**C**. Don't forget the units! - Using your formula for the force of the wind, integrate to find the work done by the wind on the paper.
