Question
**Problem Statement:**

2. Find \( v(t) \) for \( t \geq 0 \). Assume the switch has been open for a long time and is closed at \( t = 0 \).

**Circuit Diagram Description:**

The circuit consists of the following components:

- A 15 V voltage source connected in series with a 2 Ω resistor.
- A parallel branch includes:
  - A 1/3 F capacitor with a voltage across it labeled as \( v \).
  - A switch that is open for \( t < 0 \) and closes at \( t = 0 \).
- Another series branch contains:
  - A 6 Ω resistor.
  - A 7.5 V voltage source.

**Explanation:**

This question involves analyzing the transient response of a circuit when the switch closes at \( t = 0 \). The initial conditions are prior to closing the switch, where the system is assumed to have reached a steady state. Once the switch closes, the circuit dynamics will include evaluating how the capacitor voltage \( v(t) \) changes over time.
