Respuesta :

Answer:

Option A is the correct answer.

Explanation:

We know that speed is a scalar, velocity is a vector and acceleration is a vector.

So when direction of motion changes vector values also change scalar values remains the same.

Here car a car is traveling 20 kilometers an hour, then changes direction at a fork in the road. So car's speed will not change and velocity changes because of changing direction.

Option A is the correct answer.
