5. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Why didn’t the monkey (pie tin) fall underneath the arrow?

6. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Gravity affects the vertical velocity of all objects in free fall equally. The arrow fell from the (imaginary) line aimed at the pie tin.

7. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD If a bouncy ball is thrown horizontally off of a building and at the same time a different bouncy ball is dropped from the building, which will reach the ground first?

8. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Both bouncy balls will reach the ground at the same time

9. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD During the catch demonstration, at the top of the trajectory of the rubber ball, the vertical velocity was 0 m/s. What was the acceleration at the top of the trajectory?

10. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 9.8 m/s/s downward

11. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Why did the top hot wheels car land on top of the bottom hot wheels car? Daily Double!!!

12. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Horizontal velocity is constant. Even though the top hot wheels car is falling due to the acceleration of gravity, both cars move forward with a constant speed, and travel the same horizontal distance in the same amount of time.

13. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD During the paper rocket lab, if the rocket were aimed at an angle (instead of launched horizontally) it would travel a greater horizontal distance because it would be in the air ________________.

14. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD For a longer time. Having a positive initial vertical velocity, it would remain in the air for a longer period of time. And… Δx=v x (t)

15. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Vectors are added _____ to ______

16. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Tip to Tail

17. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD If the destination of an airplane is due South, but there is a wind blowing due West, what direction should the airplane fly?

18. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Southeast

19. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What is the fastest way to travel across a river if you want to reach the opposite shore in the least amount of time?

20. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Aim yourself straight across the river. This way you travel the least distance.

21. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD If an airplane is flying due East at 130 km/hr, but there is a wind heading due West at 25 km/hr, what is the resultant velocity of the plane?

22. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 105 km/hr due East

23. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Define: Vector components

24. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Vectors have both horizontal (x) and vertical (y) components. Vectors can be resolved into their components to help with vector addition and to solve projectile motion problems.

25. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What is the vertical acceleration for all horizontal launch problems?

26. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 9.8 m/s/s downward

27. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD What is the initial vertical velocity for all horizontal launch problems?

28. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 0 m/s

29. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Why do we only use the 1 st fab five formula for any questions dealing with horizontal motion during trajectory problems?

30. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Velocity is always constant in the horizontal

31. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Why is there only one time that is calculated for horizontal launch problems, when there are two times that can be calculated for launch-at-an-angle problems?

32. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD There is no time up for horizontal launch problems because the projectile STARTS out at the maximum height.

33. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Which fab five formula can be used to solve for time or distance in the vertical dimension?

34. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 4th

35. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Which angle would result in the maximum horizontal distance (range)?

36. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 45 degrees

37. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Which angle would result in the maximum vertical distance (maximum height)?

38. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 90 degrees

39. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD At the maximum height of its trajectory, the vertical velocity of a basketball is 0 m/s. If it takes the basketball 2 seconds to reach this height, how long will the basketball be in the air?

40. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 4 seconds

41. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Which angle should a punter use for a greater horizontal distance (range): 30 degrees or 60 degrees?

42. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD Since these angles are complimentary, the football would travel the same distance either way

43. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD If a soccer ball is kicked with an initial speed of 35 m/s on flat terrain, what is the speed when it lands on the ground?

44. Template by Modified by Bill Arcuri, WCSD Chad Vance, CCISD 35 m/s
