A car that is traveling west at a constant rate has speed and velocity, but no acceleration.
A car that is traveling west at a constant rate has speed and velocity, but no acceleration.
The correct answer is: velocity, but neither acceleration nor speed.
To understand this, let's define the terms:
1. Speed: a scalar quantity that refers to "how fast an object is moving". It is measured in units of distance divided by time (e.g., meters per second, miles per hour).
2. Velocity: a vector quantity that refers to "the rate at which an object changes its position". It includes both speed and direction. Velocity is also measured in units of distance divided by time (e.g., meters per second, miles per hour), but it also includes a direction (e.g., north, south, east, west).
3. Acceleration: a vector quantity that refers to "the rate at which an object changes its velocity". It includes both the change in speed and the change in direction. Acceleration is measured in units of velocity divided by time (e.g., meters per second squared, miles per hour per second).
Now, let's consider the scenario described in the question:
The car is traveling west at a constant rate. Since it is a "constant rate", it means that its speed does not change. Therefore, it has speed.
However, the car is only moving west and not changing its direction. This means that it has velocity because it has both speed and a specific direction (west). However, since it is not changing its velocity, it does not have acceleration.
So, the correct answer is that the car has velocity but neither acceleration nor speed.
