**NT6A-BCT4: Tugboat Changing Velocity I—Work & Kinetic Energy Bar Chart**

**a) Scenario:**
The velocity of a tugboat increases from 2 m/s to 4 m/s in the same direction as a force applied to the tugboat for 20 seconds.

**Task:**
Fill in the missing bars for the work & kinetic energy bar chart for this process.

**Diagram:**
- A side view illustration shows a tugboat initially moving at 2 m/s.
- 20 seconds later, the tugboat's velocity increases to 4 m/s.

**Bar Chart:**
- **Bar chart sections:**
  - **Initial system energy** includes kinetic energy (KE) represented by a bar.
  - **During** the process, work done by external forces (\(W_{\text{ext}}\)) is indicated.
  - **Final system energy** again denotes kinetic energy (KE).

- **Bar chart key:**
  - **KE**: Kinetic energy
  - **\(W_{\text{ext}}\)**: Work done by external forces

**b) Scenario:**
The velocity of a tugboat changes from 2 m/s to 4 m/s in the other direction as a force is applied to the tugboat for 20 seconds.

**Task:**
Fill in the missing bars for the work & kinetic energy bar chart for this process.

**Diagram:**
- A side view illustration shows a tugboat initially moving at 2 m/s in one direction.
- 20 seconds later, the tugboat’s velocity changes to 4 m/s in the opposite direction.

**Bar Chart:**
- **Bar chart sections:**
  - **Initial system energy** illustrates kinetic energy (KE).
  - **During** illustrates work done by external forces (\(W_{\text{ext}}\)).
  - **Final system energy** illustrates the new kinetic energy (KE).

- **Bar chart key:**
  - **KE**: Kinetic energy
  - **\(W_{\text{ext}}\)**: Work done by external forces

**Note:** Understanding these changes in kinetic energy and external work will help in analyzing how forces impact movement and energy states in real-world contexts, such as in maritime navigation.
