Question

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 segment C runs to 6 seconds 10 meters per second. Then segment D runs to 7 seconds 10 meters per second. Then segment E runs to 10 seconds 20 meters per second. The graph shows the motion of a car. Which segment shows that the car is slowing down? A B C D

Answer 1

Segment D, running from 6 seconds to 7 seconds, indicates that the car is slowing down as the velocity remains constant at 10 meters per second during this time.
