Question
**Collision of Protons in a Particle Accelerator**

**Situation Overview:**
A proton is accelerated in a particle accelerator and undergoes an elastic collision with a stationary proton in a cooled hydrogen target.

**Given Data:**
- Mass of both protons \( m_1 = m_2 = 1.672 \times 10^{-27} \, \text{kg} \)
- Initial velocity of the moving proton \( v_{1i} = 8.2 \times 10^5 \, \text{m/s} \)
- Initial velocity of the stationary proton \( v_{2i} = 0 \, \text{m/s} \)
- Angles of deflection after collision:
  - \( \theta_1 = 30^\circ \)
  - \( \theta_2 = 60^\circ \)

**Illustration Overview:**
The diagram shows the initial and final velocities and angles of the protons after the collision. The system uses a standard x-y axis for reference.

**Tasks:**

a.) **Write out the conservation equations for this collision geometry.**

b.) **Solve for the velocities of the two protons after the collision**: 
   - \( v_{1f} \) 
   - \( v_{2f} \)

c.) **Compute the velocity of the center of mass.**

This scenario involves applying principles of conservation of momentum and, since it's an elastic collision, conservation of kinetic energy as well.
