    1. Vectors Review

    2. What are the two things that make a quantity a vector?

    3. When adding vectors graphically, how should they be drawn? Head to head Tail to tail Head to tail Tip to tip

    4. When adding vectors graphically you should redraw them In the same direction as the original The same size as the original Close to the same size and direction as the original Both A and B All of the above

    5. Scalar or Vector? Speed

    6. Scalar or Vector? Displacement

    7. Scalar or Vector? Number of people in the room

    8. Scalar or Vector? 40 m at 20° from across field

    9. Scalar or Vector? 700 mL

    10. Scalar or Vector? 5 hours, 12 minutes, 18 seconds

    11. Scalar or Vector? Velocity

    12. What does the word magnitude mean?

    13. Which direction?

    14. Which direction?

    15. Which direction?

    16. You must walk 2m and 8 m in either order and in any direction. What is the smallest displacement you could have?

    17. You must walk 2m and 8 m in either order and in any direction. What is the largest displacement you could have?

    18. Given the adjacent side and the hypotenuse in a right triangle, which trigonometric function could you use?

    19. Given the adjacent and the opposite sides in a right triangle, which trigonometric function could you use?

    20. A golf ball, hit from the tee, travels 325 m in a direction 25° south of the east axis. What are the east and south components of its displacement?

    21. A car moves 65 km due east, then 45 km due west. What is its total displacement?

    22. A vector that is 1 cm long represents a displacement of 5 km. How many kilometers are represented by a 3-cm vector drawn to the same scale?

    23. An airplane flies at 200 km/hr with respect to the air. What is the velocity of the plane relative to the ground if it flies with an east-to-west, 50 km/hr cross wind?

    24. A car has a velocity of 50 km/hr in a direction 60° north of east. What are the north and east components of the vector?
