### Physics Problem: Object Breaking Apart

**Initial State (t = 0):**

- An object with mass \(2M\) is depicted moving on a frictional surface.
- Velocity of the object is \(v_0\) in opposite directions, indicating its potential to break apart symmetrically.
- The coefficient of kinetic friction is \( \mu_k \).

**Final State (t = \(\Delta t\)):**

- The object has broken into two equal pieces, each with mass \(M\).
- Both pieces slide to a stop over a distance \(L\).
- The final velocity of each piece is zero (\(v = 0\)).

**Problem Statement:**

An object of mass \(2M\) breaks apart as illustrated. The two pieces slide to rest over a distance \(L\). In terms of \(\mu_k\), \(M\), \(g\), \(L\), and \(v_0\), determine the time, \(\Delta t\), required for this process.

### Explanation:

- **Diagram Details:**
  - **Initial (i):** Shows a single object before breaking.
  - **Final (f):** Depicts two separate masses, each traveling distance \(L\) to rest.
  
This scenario involves understanding frictional force, motion equations, and using these to solve for time based on given initial conditions.
