### Problem Statement:

A 4-kg box is pushed to the right by a force of 4 N for a distance of 24 m. It has an initial velocity of 4 m/s to the right. 

**Note:** Since this problem gives the **distance** Δx traveled, **first** look at kinetic energy and calculate the **net work** using \( W_{\text{net}} = F \Delta x = \Delta K \). After the kinetic energy values are calculated, then calculate the momenta and impulse values. Remember that on quiz and test problems, you will need to decide which values should be calculated first.

6. **What is the final kinetic energy \( K_f \) of the box?**

   - **Answer Box:** 
     - **Units:** J
     - **Submission Attempts:** Tries 0/2

7. **How long \( \Delta t \) does it take for the box to travel the distance of 24 m?**

   - **Answer Box:** 
     - **Units:** s
     - **Submission Attempts:** Tries 0/2

### Explanation:
- **Initial Momentum:** Calculate using \( P_i = m \cdot v \).
- **Impulse:** \( \Delta
