_3. Lisa runs 1.5 km along a straight path and then turns and runs 2.4 km in the opposite direction. She then turns back and runs 700 m in the original direction. Let Lisa's original direction be the positive direction. What are the displacement and distance, in km, she ran? A. Displacement is 4.6 km, and distance is -0.2 km. B. Displacement is -0.2 km, and distance is 4.6 km. C. Displacement is 4.6 km, and distance is +0.2 km. D. Displacement is +0.2 km, and distance is 4.6 km. _4. Suppose a train is moving along a track. Is there a single, correct reference frame from which to describe the train's motion? A Yes, there is a single, correct frame of reference because motion is a relative term. B. Yes, there is a single, correct frame of reference which is in terms of Earth's position. D. No, there is not a single, correct frame of reference because motion is independent of frame of reference. For items 5 - 6, refer to the situation: A biker rides north for 15 km from his starting position, then turns west 16 km. _6. What is the magnitude of the biker's displacement? A 22 km В.24 km C. 26 km D. 28 km _7. What is the direction of the biker's displacement? A 47' North of West B. 43' North of West C. 38' West of North D. 52' West of North 8. Which quantities are needed to determine the average velocity of an object? A Acceleration and elapsed time B. Initial speed and final speed C. Displacement and acceleration D. Displacement and elapsed time
