Final answer:
The average velocity of the car is zero because it ends up at the starting point after traveling around a circular track, making displacement zero. If calculating average speed, it would be 50.0 m/s by dividing the total distance of 2500 meters by the total time of 50 seconds.
Step-by-step explanation:
To calculate the average velocity of the car, we need to understand the concept of velocity as a vector quantity, which has both magnitude and direction. In this case, because the car travels around a circular track and returns to its starting point, the displacement is zero. Therefore, the average velocity of the car is also zero. However, if the question is referring to the average speed, we can calculate it using the formula:
Average speed = Total distance / Total time
Here, the car travels a total distance of 2500 meters in 50.0 seconds.
Average speed = 2500 meters / 50.0 seconds = 50.0 m/s.
Thus, the average speed of the car during this time is 50.0 m/s, which corresponds to Option 2.
