Question
**Problem Statement:**

Q2. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of \( m_A = 23 \, \text{Mg} \) and \( m_B = 14 \, \text{Mg} \), respectively. The directions of their initial velocities are shown in the image, and the speeds are \( v_{A,1} = 4.3 \, \text{m/s} \) and \( v_{B,1} = 2.9 \, \text{m/s} \). Determine the velocity of A after collision if the cars collide and rebound, such that B moves to the right with a speed of 1.8 m/s. Right is considered the positive direction and negative sign must be included if A moves to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit.

**Diagram Explanation:**

The diagram consists of two freight cars, A and B, on parallel tracks. 

- **Freight Car A**: It is shown moving to the right with an initial velocity of \( v_{A,1} \).
- **Freight Car B**: It is shown moving to the left with an initial velocity of \( v_{B,1} \).

**Your Answer:**

A field is provided for the answer where the velocity of A after the collision should be recorded, formatted to three decimal places with the appropriate units.

**Answer Fields:**

- "Answer" (Numeric value)
- "Units" (Appropriate SI unit)
