**Physics Problem: Momentum and Vector Analysis**

An object of mass \(3M\), moving in the \(+x\) direction at speed \(v_0\), breaks into two pieces of mass \(M\) and \(2M\) as shown in the figure.

If \(\theta_1 = 69.0^\circ\) and \(\theta_2 = 22.0^\circ\), determine the final velocities \(v_1\) and \(v_2\) of the resulting pieces in terms of \(v_0\).

- **Diagram Explanation:**
  - The initial object with mass \(3M\) is depicted as a large blue sphere moving rightward with velocity \(v_0\).
  - After breaking, it splits into two smaller spheres:
    - A green sphere with mass \(2M\).
    - An orange sphere with mass \(M\).
  - The angle \(\theta_1\) is shown as the angle made by the \(M\) piece with the x-axis and is \(69.0^\circ\).
  - The angle \(\theta_2\) is shown as the angle made by the \(2M\) piece with the x-axis and is \(22.0^\circ\).

- **Equations for Final Velocities:**
  - Velocity \(v_1\) for mass \(M\) is given as:
    \[
    v_1 = \text{Incorrect value shown as } 1.155 \, v_0
    \]
  - Velocity \(v_2\) for mass \(2M\) is calculated as:
    \[
    v_2 = 1.4 \, v_0
    \]

**Note to Students:**
- Ensure to use momentum conservation and vector component analysis to correctly derive \(v_1\) and \(v_2\). 
- Re-calculate if required, keeping in mind the system's momentum before and after the explosion must be equal, decomposing the problem into x and y components.
