Transcribed Image Text:**Collision Analysis of a Car and Truck**
**Scenario Description:**
A car with a mass of 1,130.0 kg is traveling eastward at a speed of 25.000 m/s. It collides with a truck weighing 9,300.0 kg, also moving eastward at 20.000 m/s. Post-collision, the car's velocity is 18.000 m/s east.
**Diagram Explanation:**
The diagram illustrates two scenarios:
1. **Before Collision:** The car and truck are shown separately with velocities \( v_{Ci} \) and \( v_{Ti} \) indicating the initial velocities of the car and truck, respectively.
2. **After Collision:** The car and truck are depicted closer, with velocities \( v_{Cf} \) and \( v_{Tf} \) representing the final velocities after the collision.
**Questions and Responses:**
**(a) Truck's Velocity Post-Collision:**
- Question: What is the velocity of the truck right after the collision? Provide your answer to five significant figures.
- Response: The entered value is 20.85 m/s east. *Check the number of significant figures.*
**(b) Change in Mechanical Energy:**
- Question: What is the change in mechanical energy of the car-truck system during the collision?
- Response: Input is 8605.375. *The response has the wrong sign.*
**(c) Explanation of Energy Change:**
- Additional Information: Provide an account for the change in mechanical energy.
- Response: Energy is converted into heat energy.
**Footnote:**
Ensure to verify the calculations for the correct number of significant figures and signs. Consider the principles of conservation of momentum and energy transformations in collision scenarios.
