Unformatted text preview: (1) AB 19. During the interval t = 8.0 seconds to t = 10.0 seconds, the speed of the object is (3) decreasing 20. What is the maximum speed attained by the object during the 10.0 seconds of travel? 25 m/s 21. The graph below represents the relationship between distance and time of travel for an object moving in a straight line. Determine the instantaneous speed of the object at 1.5 seconds. 2.5m / 1.5s = 1.7 m/s 22. A boat heads directly eastward across a river at 12 meters per second. If the current in the river is flowing at 5.0 meters per second due south, what is the magnitude of the boats resultant velocity? (2) 13 m/s 23. Which par of graphs represents the same motion? (3) 24. The graph below represents the motion of a body moving along a straight line. Which quantity related to the motion of the body is constant? (3) acceleration...
