Consider the motion diagram. It illustrates a car's velocity (V) and acceleration (A). Determine is there is a change in either
aleksandrvk [35]

Answer:

Change in velocity: yes

Change in acceleration: no

Explanation:

The diagram of the problem is missing: find it in attachment.

In the diagram, there are represented:

- The velocity of the car, as a vector labelled with V

- The acceleration of the car, as a vector labelled with A

The directions of the vector represent the direction of the velocity and the acceleration, while the length of the arrows represent the magnitude of the two quantities.

We observe that:

- For the velocity, the direction is always to the right; however, the length of the arrow decreases, so the magnitude of the velocity keeps decreasing

- For the acceleration, the direction is always to the left; and the length of the arrow remains constant, therefore the magnitude of the acceleration does not change.

This means that the car is moving to the right, but it is slowing  down, since the direction of the acceleration is opposite to the direction of the velocity.
