Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

### Educational Website Transcription:

#### Problem Statement

**Disk System Dynamics**

Disk \( D \) turns with a constant clockwise angular velocity of 36 rad/s. Disk \( E \) has a weight of 60 lb and is initially at rest when it is brought into contact with \( D \). The coefficient of kinetic friction between the two disks is \( \mu_k = 0.3 \). Neglect the weight of bar \( BC \). Refer to Figure 1.

#### Task

**Determine the Time for Angular Velocity Convergence**

Determine the time required for disk \( E \) to attain the same angular velocity as disk \( D \).

**Instructions:**

Express your answer to three significant figures and include the appropriate units.

---

### Diagram Explanation

**Figure 1:**

- The diagram shows two disks, \( D \) and \( E \).
- Disk \( D \) is rotating with an angular velocity of 36 rad/s.
- Disk \( E \), weighing 60 lb, is initially at rest and is shown engaging with disk \( D \).
- The system includes a vertical bar labeled \( BC \), which is connected to disk \( E \). The bar \( BC \) is 2 ft long, and the distance from the bar to the center of each disk is 1 ft.
- The attachment allows disk \( E \) to rotate when in contact with disk \( D \).

#### Additional Notes

- The problem requires you to consider the effects of kinetic friction (with a coefficient of \( \mu_k = 0.3 \)) in the interaction between the two disks.
- Neglect any impact from the weight of the bar \( BC \).
