Which graph best represents a car starting from rest, accelerating, cruising, and then braking?

The hill-shaped graph effectively depicts the scenario of a car starting from rest, accelerating, cruising at a constant speed, and then braking.

Initially, as the car starts from rest, the graph would show a rise in height, representing the acceleration of the car. This portion illustrates the increase in velocity as the car speeds up.

Once the car reaches its cruising speed, the graph becomes flat, which signifies that the velocity remains constant over time. This flat section indicates that the car is moving at a steady speed without any acceleration or deceleration.

Finally, during the braking phase, the graph slopes downward, representing the decrease in velocity as the car slows down. This part of the graph captures the negative acceleration (or deceleration) as the brakes are applied.

The combination of these segments creates a graph that resembles a hill shape, effectively capturing the different phases of motion experienced by the car—starting, cruising, and slowing down.
