AI Generated Solution

To understand why the person driving the car falls forward and hits his head against the steering wheel after suddenly applying the brakes, we can analyze the situation using the concept of inertia and the laws of motion. ### Step-by-Step Solution: 1. **Initial Situation**: The car is moving forward with an initial velocity \( u_0 \). The driver is seated inside the car, and his lower body is in contact with the car seat. 2. **Applying the Brakes**: When the driver sees a child on the road and suddenly applies the brakes, the car begins to decelerate rapidly. The brakes cause the car to come to a stop. ...
