**Kinematics and Energy Conservation Problem**

**Scenario Description:**

A 12.5-kg crate slides along a horizontal frictionless surface at a constant speed of 4.0 m/s. The crate then slides down a frictionless incline and across a second horizontal surface as illustrated in the figure.

**Diagram Explanation:**

The diagram shows:

1. **Initial Horizontal Surface:**
   - A 12.5-kg crate moves on this surface at 4.0 m/s.

2. **Incline:**
   - The incline is frictionless, has a vertical height of 3.0 m, and a horizontal length of 4.0 m.

3. **Second Horizontal Surface:**
   - The crate continues to move after descending the incline.

This setup is often used to analyze principles related to energy conservation and kinematics, including potential and kinetic energy transformations.

**Question 13: Speed of the Crate**

What is the speed of the crate when it arrives at the lower surface?

A) 7.7 m/s  
B) 8.6 m/s  
C) 59 m/s  
D) 75 m/s  
E) 98 m/s  

*Note: This multiple-choice question aims to test understanding of physics principles relating to motion and speed. It may involve calculations using equations of motion or energy conservation principles.*
