To analyze the graph's description and determine which statement best describes Carla's motion, let's break down the information:
-
Velocity Decrease: The graph shows a decreasing trend in the velocity during the initial part of the trip (from 15 m/s at 0 seconds to 4 m/s at 3 seconds).
-
Stopping Point: At 4 seconds, the velocity reaches 0 m/s, indicating that Carla stops.
-
Subsequent Increase: From 4 seconds to 6 seconds, the velocity then increases from 0 m/s to 4 m/s.
From this analysis, we can summarize Carla's motion as follows:
- She started at a high velocity (15 m/s) and then decreased her speed, slowing down until she came to a stop (0 m/s).
- After stopping, she then began to speed up again, moving from 0 m/s to 4 m/s.
Evaluating the Statements:
-
Carla sped up in the beginning of her trip, stopped, and then slowed down.
This statement is incorrect because she slowed down in the beginning, not sped up. -
Carla had a greater acceleration in the beginning than in the end.
This statement lacks clarity as we cannot determine exact accelerations from the graph. -
Carla slowed down in the beginning of her trip, stopped, and then sped up.
This statement is correct as it accurately reflects her motion. -
Carla had a continuous acceleration throughout the entire trip.
This statement is incorrect because her motion involves both deceleration and acceleration, not continuous acceleration.
Conclusion:
The best description of the graph is: Carla slowed down in the beginning of her trip, stopped, and then sped up.
