Consider the process shown in (Figure 1). Suppose E1 = 1 J.

What is the final kinetic energy of the system for the process shown in the figure?

 

**Energy Bar Chart Explanation**

The bar chart illustrates an energy equation with various forms of energy present in a system. The vertical axis is labeled \( E (J) \), representing energy in joules. Specific energy levels are marked as \( 0 \), \( E_1 \), \( 2E_1 \), \( 3E_1 \), and \( 4E_1 \).

The equation shown is: 

\[ K_i + U_i + W_{ext} = K_f + U_f + \Delta E_{th} \]

**Left Side of the Equation:**

- **\( K_i \) (Initial Kinetic Energy):** Represented by a small green bar, indicating a low amount of initial kinetic energy.
- **\( U_i \) (Initial Potential Energy):** Represented by a slightly larger blue bar compared to \( K_i \).
- **\( W_{ext} \) (Work Done by External Forces):** Represented by a tall purple bar, showing a significant amount of work done on the system by external forces.

**Right Side of the Equation:**

- **\( K_f \) (Final Kinetic Energy):** The energy corresponding to \( K_i \) is substituted with a question mark, signifying uncertainty or something to solve for.
- **\( U_f \) (Final Potential Energy):** Represented by a tall blue bar, larger than \( U_i \), indicating an increase in potential energy in the final state.
- **\( \Delta E_{th} \) (Change in Thermal Energy):** Represented by a small orange bar, showing the conversion of some energy into thermal energy due to, perhaps, friction or other dissipative forces.

The bar chart is a visual representation to help understand the energy transformations and transfers in a given system.
