The graph depicts the velocity and times of Elan and Anna during a race.
A graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). A green line labeled Anna runs in straight segments from 0 seconds 0 meters per second to 1 second 6 meters per second to 10 seconds 24 meters per second. A red line labeled Elan runs in straight segments from 0 seconds 0 meters for second to 1 second 1 meter per second to 3 seconds 10 meters per second to 6 seconds 10 meters per second to 8 seconds 20 meters per second to 10 seconds 25 meters per second.
Which best depicts the data?
From 0 to 2 seconds, Anna experienced negative acceleration.
From 3 to 6 seconds, Elan accelerated while Anna did not.
From 6 to 8 seconds, Elan accelerated faster than Anna.
From 8 to 10 seconds, Elan experienced negative acceleration.
This best depicts the data shown in the graph:
- From 0 to 2 seconds, Anna experienced negative acceleration as her velocity increased at a decreasing rate.
- From 3 to 6 seconds, Elan accelerated while Anna did not, as Elan's velocity increased steadily during this time period.
- From 6 to 8 seconds, Elan accelerated faster than Anna, as his velocity increased at a higher rate compared to Anna's.
- From 8 to 10 seconds, Elan experienced negative acceleration as his velocity decreased towards the end of the race.
