A graph titled velocity versus time has horizontal axis time (seconds) and vertical axis velocity (meters per second). A line has 5 straight segments. Line segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second. Then segment B runs to 3 seconds 30 meters per second. Then an unlabeled segment runs to 4 seconds 40 meters per second. Then an unlabeled segment runs to 5 seconds 40 meters per second. Then segment C runs to 6 seconds 10 meters per second. Then segment D runs to 7 seconds 10 meters per second. Then an unlabeled segment runs to 8 seconds 40 meters per second. Then an unlabeled segment runs to 9 seconds 40 meters per second. Then segment E runs to 10 seconds 20 meters per second. What is the acceleration of the car at segment C? 30 m/s2 –30 m/s2 40 m/s2 –40 m/s2
