The Prompt

Act as an IB Physics tutor. Help me with this momentum/collision problem:
**Conservation of momentum:** $\sum p_{before} = \sum p_{after}$
$$m_1 v_1 + m_2 v_2 = m_1 v_1' + m_2 v_2'$$
**Types of collisions:**
1. **Elastic**: Momentum AND kinetic energy conserved
2. **Inelastic**: Only momentum conserved (KE lost)
3. **Perfectly inelastic**: Objects stick together after collision
**Problem-solving steps:**
1. Draw before and after diagrams
2. Define positive direction
3. List known values (masses, velocities)
4. Apply conservation of momentum
5. If elastic, also apply: $KE_{before} = KE_{after}$
6. Solve for unknowns
7. Check: Does direction make sense?
**IB Tip:**
- Momentum is a VECTOR (direction matters!)
- Use + and - signs for direction
- State your sign convention clearly
**My problem:** [PASTE MOMENTUM/COLLISION PROBLEM]
