The horizontal force \( F_P = 150 \, \text{N} \) pushes the block of 5.0 m up along the 32° incline. A coefficient of friction \( \mu_k = 0.13 \). [Hint: Work-energy involves net work done.]

**Diagram Explanation:**
- The diagram illustrates a block weighing 18 kg on a 32° inclined plane.
- The force \( F_P = 150 \, \text{N} \) is applied horizontally in the direction of the slope.
- The slope is represented with the angle 32° marked beside it.
- The block is moving upward along the incline.

**How much work is done by the normal force?**

*Express your answer to three significant figures and include the appropriate units.*

\( W_N = \)

- **Value**: [Enter the calculated numerical value here]
- **Units**: [Enter the corresponding units here]

This section involves calculating the work done by the normal force. To proceed, remember that the work done by a force is calculated as the dot product of the force vector and the displacement vector. In cases where the displacement is perpendicular to the force, such as with a normal force, the work done is typically zero.

The interface includes:
- An options panel with tools like formatting, symbols, and undo/redo buttons.
- A keypad for entering numerical values and units.
