The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Scenario**: A car is moving forward at a high speed. When the driver suddenly applies the brakes, the car begins to decelerate rapidly. 2. **Identifying the Forces at Play**: According to Newton's First Law of Motion, an object in motion will remain in motion unless acted upon by an external force. In this case, the car is the object that is being acted upon by the brakes. 3. **Analyzing the Passengers' Motion**: The passengers inside the car are initially moving at the same speed as the car. When the brakes are applied, the car slows down due to the friction between the brakes and the wheels, but the passengers, not being physically attached to the car, will continue moving forward at the original speed. 4. **Applying the Concept of Inertia**: The passengers experience inertia, which is the tendency of an object to resist changes in its state of motion. Since the passengers are not secured in their seats, they will continue to move forward while the car stops. 5. **Conclusion**: As a result, when the brakes are applied, the passengers will lurch forward due to their inertia. Therefore, the correct answer to the question is that the passengers will fall forward. ---
