The correct response is: speed, but neither velocity nor acceleration.

Answer 3

[AI-generated answer — Explain Bot]

The correct answer is "speed, but neither velocity nor acceleration."

To understand why, let's break it down:

1. Speed: Speed is a scalar quantity that represents how fast an object is moving. It is the magnitude of velocity, which means it only considers the magnitude of the motion, not the direction. In this case, the car is traveling west at a constant rate, so it has a certain speed.

2. Velocity: Velocity is a vector quantity that combines both the speed and direction of an object's motion. It includes both the magnitude (speed) and the direction. For example, velocity can be described as "50 km/h westward." In the given scenario, the car is traveling west, so it has a velocity.

3. Acceleration: Acceleration is the rate at which an object's velocity changes over time. It accounts for both the change in speed and direction. If the car were speeding up, slowing down, or changing its direction while traveling west, it would have acceleration. However, since the question states that the car is traveling at a constant rate (indicating no change in velocity), it has no acceleration.

Therefore, the car has speed (because it is moving at a certain rate) but does not have velocity (as velocity includes the direction) or acceleration (as there is no change in velocity).
