### Collision Analysis: Car and Truck System**Scenario Overview:**A collision scenario involves a 115.0 kg car traveling east with an initial speed of 25.000 m/s colliding with a 10,000.0 kg truck moving in the same direction at 20.000 m/s. After the collision, the car's velocity is 18.000 m/s east.**Diagram Explanation:**- **Before Collision:** The diagram shows two separate vehicles. The car, on the left, is moving faster than the truck, on the right.- **After Collision:** Both vehicles are closer, indicating an interaction. The car’s speed decreases, and the truck's speed changes.**Questions and Solutions:****(a) Determine the Truck's Velocity Post-Collision:**- **Given Answer:** 20.3 m/s east**(b) Calculate the Change in Mechanical Energy of the System:**- It is implied that the initial calculation was incorrect, as indicated by the response: "Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully."**(c) Justify the Change in Mechanical Energy:**- Explanation required for energy conservation and transformations involved during the collision. The explanation box is currently unfilled.**Note:** Responses that require further calculation or reasoning should ensure correct application of momentum and energy conservation principles.
