A dog runs for 2 seconds without stopping. After 1 second, the dog travels 6 meters. By the end of the next second, the dog has traveled an additional 4 meter. Which best describes the motion of the dog during the two seconds?
So at first, the dog moved 6 meters in one second (velocity = 6 meters/second) then moves 4 meters in one second (velocity = 4 meters/second). You need acceleration or something?
This question indicates you choose the “best” description is from a list. You need to include these when you post this type of question; else, no one will know how to answer your question properly. (Unless that person has mind reading skills, like some of us genetically enhanced chimps).
