Answer 2

Answer:

The dog was stopped for 4 seconds.

Explanation:

In this case, a dog runs out of the back door of a house and stops to grab a bone. Then the dog returned to the house. The attached graph shows the motion of the dog. It is a position time graph.

For 4 seconds, the dog moves in uniform motion. From 4 second to 8 second the dog is at rest. From 8 seconds, the dog decreases its velocity and at approximately 10.5 seconds it comes to rest.

So, for 4 seconds the dog was stopped. Hence, the correct option is (b).
