Question

the graph represents velocity vs. time for carla. which best describes the graph? carla sped up in the beginning of her trip, stopped, and then slowed down. carla had a greater acceleration in the beginning than in the end. carla slowed down in the beginning of her trip, stopped, and then sped up. carla had a continuous acceleration throughout the entire trip.

Explanation:

Step1: Analyze the start of the graph

The velocity - time graph starts with a decreasing slope, which means the velocity is decreasing. So Carla is slowing down at the beginning.

Step2: Analyze the middle part

At time \(t = 4\) seconds, the velocity is \(0\), which means Carla has stopped.

Step3: Analyze the end part

After \(t = 4\) seconds, the velocity starts to increase, which means Carla is speeding up.

Answer:

Carla slowed down in the beginning of her trip, stopped, and then sped up.
