Question

select the correct answer. these two particle motion diagrams for car a and car b have the same time interval. what do the diagrams indicate? car a and car b reached the destination at the same time. car b reached the destination before car a. car a reached the destination before car b. car a is stuck in traffic.

Explanation:

In particle - motion diagrams, the number of time intervals (represented by the number of gaps between the car positions) can be used to compare the time taken. Car A has more time intervals (4 gaps between 5 cars) compared to car B (2 gaps between 3 cars) to reach the destination. Since the time interval for each step is the same, the car with fewer time intervals takes less time.

Answer:

Car B reached the destination before car A.
