1) Which combination of statements is most accurate? [Enter your answer as a string of the letter options you believe are correct. For instance, if you think options A, D, and E are correct then enter "ADE". NOTE: There are only 5 tries for this problem.] A) Your velocity may point in a different direction from the one in which you are moving B) The value of your total displacement for any round-trip is zero. C) The value of your total distance for any round-trip is zero since you come back to where you started. D) During a round-trip, your speed must change E) None of the above Answer: Submit All Answers 2) Below are a series of arrows depicting an object's velocity vector (green arrow) and an object's acceleration vector (red arrow). Choose all combinations in which the object's speed is decreasing. [Enter your answer as a string of the letter options you believe are correct. For instance, if you think options A, D, and E are correct, then enter "ADE"] E) None of the above Answer: Submit All AnswersExplanation / Answer
1] B - displacement of the round trip is zero not distance. During a round trip it can have constant speed.
2] ABC
In ABC the velocity and acceleration have more than 90 degree angle between them, so speed must decrease.
