Unformatted text preview: 3. If we reduce the time interval the car only moves to B’ rather than B. Draw the displacement vector for the car moving from A to B’. What mathematical word describes the relation between the displacement vector and the trajectory as the points approach each other? 4. What is the direction of the instantaneous velocity relative to the trajectory at any point? Draw and label vectors showing the instantaneous velocities at points A and B. Does your answer depend on whether the object is speeding up, slowing down, or moving at constant speed? B . Suppose you choose a different origin. Which of these vectors would change, which would stay the same. Position of A, position of B, displacement from A to B, instantaneous velocity at B. A B’ B...
