speed, but neither velocity nor acceleration.
A car that is traveling west at a constant rate has velocity, but neither acceleration nor speed.
The correct answer is "velocity, but neither acceleration nor speed."
To understand why, let's break down the definitions of speed, velocity, and acceleration:
1. Speed: Speed refers to the rate at which an object covers distance. It is a scalar quantity and is represented by a number and the appropriate unit of measurement (e.g. 50 km/h). Speed does not involve direction.
2. Velocity: Velocity is also the rate at which an object covers distance, but it includes direction as well. It is a vector quantity and is represented by a number, unit of measurement, and a direction (e.g. 50 km/h west). Velocity takes into account both speed and the direction of motion.
3. Acceleration: Acceleration is the change in velocity over time. It describes how quickly an object's speed or direction changes. Like velocity, it is also a vector quantity and includes both a number and a direction.
Now, let's apply these definitions to the given scenario:
The car is traveling west at a "constant rate." This means that the car's speed remains the same over time, indicating that it has a constant velocity since velocity includes both speed and direction. However, since the car is not described as accelerating or changing its velocity, it means that it has neither acceleration nor speed changes. Therefore, the car has velocity, but no acceleration or speed changes.
Hence, the correct answer is "velocity, but neither acceleration nor speed."
