Question

use the graph below to answer the question. which description best matches the motion shown in the graph? an object moves at a constant speed then stops. an object moves at a constant speed then accelerates. an object accelerates and then moves at a constant speed. an object accelerates then stops.

Explanation:

Step1: Analyze the first part of the graph

In a distance - time graph, the slope represents speed. The first part of the graph has a non - zero constant slope. A non - zero constant slope in a distance - time graph means the object is moving at a constant speed.

Step2: Analyze the second part of the graph

The second part of the graph has a slope of zero. A slope of zero in a distance - time graph means the distance is not changing with time. When the distance does not change with time, the object is at rest (stopped).

Answer:

A. An object moves at a constant speed then stops.
