### Simple Pendulum and Simple Harmonic Motion

A simple pendulum with a length of 2.23 meters and a mass of 6.74 kg is given an initial speed of 2.06 meters per second (m/s) at its equilibrium position. The pendulum undergoes simple harmonic motion. 

#### Problems to Solve:
1. **Period (T)**:
   - The time taken for one complete cycle of the pendulum's swing.
2. **Total Energy (E)**:
   - The sum of the kinetic and potential energy in the system.
3. **Maximum Angular Displacement (θ_max)**:
   - The furthest angle from the equilibrium position the pendulum reaches.
4. **Equation for Angular Position as a Function of Time**:
   - This expresses the pendulum's angular displacement over time.

#### Solutions:
- **Period (T)**:
  \( T = 3.00 \, \text{s} \)
  
- **Total Energy (E)**:
  \( E = 14.3 \, \text{J} \)
  
- **Maximum Angular Displacement (θ_max)**:
  \( \theta_{\text{max}} = 0.441 \, \text{rad} \)
  
- **Equation for Angular Position (θ)**:
  \[
  \theta(t) = 0.441 \, \text{rad} \sin(2.10 \, \text{s}^{-1} t)
  \]

The equation above shows that the pendulum's angular position oscillates as a sine function, where:
- \( 0.441 \, \text{rad} \) is the amplitude,
- \( 2.10 \, \text{s}^{-1} \) is the angular frequency,
- \( t \) is the time variable.

### Explanation of Key Terms:
- **Simple Harmonic Motion**:
  - This is the type of oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that displacement.
- **Angular Displacement (θ)**:
  - The angle through which the pendulum has swung from its equilibrium (rest) position.
- **Amplitude**:
  - The maximum displacement from the equilibrium position in simple harmonic motion.
- **Angular Frequency (ω)**:
  - Related to the period, it describes how many oscillations occur in a unit of time.

This model assumes
