5 0

Answer:

The answer to your question is: c

Explanation:

a) The car stops moving.  The statement is true because fromthe interval 5 to 10 s, the car does not move.

b) The car changes direction. This statement is true because from 0 to 5 seconds, the vehicle is moving away from the origin and from 10 to 12.5 is getting closer to the origin.

c) The speed of the car is constant during the trip. This sentence is wrong because from 0 to 5 is moving with one velocity and from 10 to 12.5 is moving with a different velocity.

d) The car returns to the starting point of the trip. This sentence is correct, the movement starts at displacement equals to zero and ends at the same displacement.
