The average velocity can be found by calculating the total displacement of the car and dividing it by the total time.
The car's average velocity is "4 m/s west".
First, we will find the total displacement as follows:
Total Displacement = 20 m (East) + 40 m (West)
Taking East direction as positive and west direction as negative, we get:
Total Diplacement = 20 m - 40 m
Total Displacement = - 20 m = 20 m (West)
Now, the average velocity of the car will be:
[tex]Average\ Velocity = \frac{Total\ Displacement}{Total\ Time}\\\\Average\ Velocity = \frac{20\ m\ (West)}{5\ s}\\\\[/tex]
Average Velocity = 4 m/s west
The attached picture shows the description of average velocity.
