Question
**Engineering Physics 1 - Problem 7.43**

A 2.2 kg piece of wood slides on the surface shown in Figure 1. The curved sides are perfectly smooth, but the rough horizontal bottom is 35 m long and has a kinetic friction coefficient of 0.30 with the wood. The piece of wood starts from rest 4.0 m above the rough bottom.

### Problem Statement:

**Figure Explanation:**

- **Diagram:** The image depicts a smooth curved surface leading into a rough horizontal bottom labeled as “Wood” and “Rough bottom”.

### Questions:

**Part A:**
Where will this wood eventually come to rest?

- **Express your answer in meters.**
- Input box labeled as "s = ____ m"

**Part B:**
For the motion from the initial release until the piece of wood comes to rest, what is the total amount of work done by friction?

- **Express your answer in joules.**
- Input box labeled as "W = ____ J"
