Answer:
The car must be moving at a changing velocity but at a constant speed. This is caused when an object is changing direction but not its speed.
Step-by-step explanation:
Since velocity is a vector, it is measured with both magnitude (the numerical value) and direction. Acceleration is the change in velocity over a time period, which makes acceleration also a vector.
Speed is a scalar, so it is only measured by its magnitude (the numerical value). Speed only changes if you:
1. slow down
2. speed up
There are 3 ways an object can accelerate:
1. by slowing down
2. by speeding up
3. by changing direction (turning)
Since the speed is the same, that means the car can't be speeding up or slowing down. Therefore, the car must be turning direction with a constant speed.
