4
$100 Question: Vectors What is Y?

5
$ Vector Components The Pythagorean Theorem

6
$200 Question: Vectors What is A 2 + B 2 = C 2

7
$ Vectors For a right triangle, if a = 5 and b = 12, this is what c =.

8
$300 Question: Vectors What is 13?

9
$ Vectors If 0.6 is the proportion of V 0 in the horizontal And V 0 is 14 m/s, this is V 0X.

10
$400 Question: Vectors What is 8.4 m/s?

11
$ Vectors If 0.8 is the proportion of V 0 in the vertical And V 0 is 13 m/s, this is V 0Y.

12
$500 Question: Vector Components What is 10.4 m/s?

13
$100 – 1-D Holdover This is the equation for average speed.

14
$100 Question: 1-D Holdover What is S avg = d/t?

15
$ D Holdover This is the equation for distance of free fall.

16
$200 Question: 1-D Holdover What is d = ½ gt 2 ?

17
$ D Holdover This is the equation for average acceleration.

18
$300 Question: 1-D Holdover What is a = Δv/ Δ t?

19
$ D Holdover This is the significance of negative acceleration

20
$400 Question: 1-D Holdover What is deceleration or slowing down?

21
$ D Holdover This is the usual value of acceleration HORIZONTALLY for a projectile.

22
$500 Question: Equations What is 0 m/s 2 ?

23
$ Concepts When a projectile is moving upwards, this is The direction the acceleration points.

24
$100 Question: Concepts What is downward?

25
$ Concepts When a projectile reaches the highest point Of its trajectory, this is its vertical speed.

26
$200 Question: Concepts What is 0 m/s?

27
$ Concepts Of ‘independent’ or ‘dependent, it describes How horizontal and vertical motion of a Projectile are related to one another.

28
$300 Question: Concepts What is independent?

29
$ Concepts This is the speed of a ball on its way down (when it passes your hand) if it is thrown straight up into the air with a speed of V 0.

30
$400 Question: Concepts What is V 0 ?

31
$ Concepts This is the point in a projectile’s trajectory when It is moving the slowest.

32
$500 Question: Concepts What is at the apex or top?

33
$ Calculations If a ball is thrown upward with a speed of V 0Y = 20 m/s, this is how long it will take for It to reach its max height.

34
$100 Question: Calculations What is 2.04 sec?

35
$ Calculations If a ball is thrown upward with a speed of V 0Y = 20 m/s, this is how long it will take for It to hit the ground.

36
$200 Question: Calculations What is 4.08 sec?

37
$ Calculations If a ball is thrown upward with a speed of V 0Y = 20 m/s, this is its max height.

38
$300 Question: Calculations What is 20.4m?

39
$ Calculations If a ball is thrown such that the proportion of Its speed in the horizontal is 1/3 V 0 and V0 = 18 m/s, this is how far the ball will go horizontally in 2 sec.

40
$400 Question: Calculations What is 12 m?

41
$ Calculations If a ball is thrown such that the proportion of Its speed in the vertical direction is 1/4 V 0 and V 0 = 40 m/s, this is how long it will take the ball To reach its apex.

42
$500 Question: Calculations What is 1.02 sec?

43
$100 – Pictures If the V 0 vectors in these three graphs are the same Magnitude, this graph corresponds to a trajectory With the highest max height.

44
$100 Question: Pictures What is the one on the left?

45
$ Pictures If the V 0 vectors in these three graphs are the same Magnitude, this graph corresponds to a trajectory With the maximum range.

46
$200 Question: Pictures What is the middle one?

47
$ Pictures If the V 0 vectors in these three graphs are the same Magnitude, this graph corresponds to a trajectory With the lowest max height.

48
$300 Question: Pictures What is the one on the right?

49
