Answer :
Final answer:
The average speed of the car on its entire trip can be calculated by dividing the total distance traveled (209,000 meters) by the total time spent (5000 seconds), resulting in an average speed of 41.8 m/s.
Explanation:
In Physics, the average speed of an object is defined as the total distance traveled divided by the total time spent traveling. In this case, the total distance covered during the trip is the sum of the distances covered during each leg of the trip. The total time is the sum of the time spent in each leg. In the first leg, the car travels 55 m/s for 2000 s, covering a distance of 55 * 2000 = 110,000 m to the right. In the second leg, the car travels 33 m/s for 3000 s, covering a distance of 33 * 3000 = 99,000 m to the left. The total distance covered is the sum of these two distances, 110,000 + 99,000 = 209,000 m. The total time is 2000 s + 3000 s = 5000 s.
Therefore, the average speed for the entire trip becomes 209,000 m / 5000 s = 41.8 m/s.
