Question

3-4 CHAPTER 3 Vectors and Motion in Two Dimensions 3.4 Motion in Two Dimensions 25. The figure below shows the positions of a moving object at three successive points in a motion diagram. Draw and label the velocity vector in for the motion from 0 to 1 and the vector for the motion from 1 to 2. Then determine and draw the vector vi-vo with its tail on point 1. 26. A car enters an icy intersection traveling 16 m/s due north. After a collision with a truck, the car slides away moving 12 m/s due east. Draw arrows on the picture below to show (i) the car's velocity vo when entering the intersection, (ii) its velocity V when leaving, and (iii) the car's change in velocity ,-Vo due to the collision. Exercises 27-28: The figures below show an object's position at three successive points in a motion diagram. For each diagram: . Draw and label the initial and final velocity vectors Vo and Vi. Use black. . Use the steps of Tactics Box 3.3 to find the change in velocity Av. Draw and label a at the proper location on the motion diagram. Use red. Is the object speeding up, slowing down, or moving at a constant speed? Write your answer beside the diagram. 27. 28.
