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.

a. 4.52 m/s south

Velocity is a vector, whose magnitude is defined as the ratio between the displacement of the object and the time taken for the displacement to occur:

v=\frac{d}{t}

where

d is the displacement

t is the time

Velocity is a vector, so it also has a direction, which corresponds to that of the displacement.

For the ball in this problem,

d = 9.5 m south

t = 2.1 s

Substituting, we find:

v=\frac{9.5}{2.1}=4.52 m/s

and the directiion is the same as the displacement (south).

b. 4.52 m/s north

For this part, we must keep in mind that the speed is the magnitude of the velocity; however, speed is a scalar, so it does not have a direction.

Here we are told that the tennis ball travels at constant speed, so on its way back from Liam to Katie the ball's velocity is still the same as before, therefore

|v| = 4.52 m/s

However, this time the direction is opposite to before, since the ball is travelling in the opposite direction.

Therefore, the ball's velocity when Liam returns Katie's service is

4.52 m/s north
