B) Games Won
Explanation:
On the vertical y-axis, the number of games won would be labelled.
- It is a common practice in science to put the dependent variables on the y-axis.
- The independent variables are drawn on the x-axis.
- In this problem, the number of games won is the dependent variable.
- The number of years is independent. It is fixed.

Answer:
56.0 m
Explanation:
We know that after 0.510 s, the ball is level with Bob again. We can use this to find the vertical component of the initial velocity.
y = y₀ + v₀ᵧ t + ½ gt²
h+2 = h+2 + v₀ᵧ (0.510) + ½ (-9.8) (0.510)²
v₀ᵧ = 2.50 m/s
Since the magnitude is 34.1 m/s, we can now find the horizontal component:
v₀² = v₀ₓ² + v₀ᵧ²
(34.1)² = v₀ₓ² + (2.50)²
v₀ₓ = 34.0 m/s
And since we know the ball lands 126 m from the base of the cliff, we can find the time it takes to land:
x = x₀ + v₀ₓ t + ½ at²
126 = 0 + (34.0) t + ½ (0) t²
t = 3.71 s
Finally, we can now find the height of the cliff:
y = y₀ + v₀ᵧ t + ½ gt²
0 = h+2 + (2.50) (3.71) + ½ (-9.8) (3.71)²
h = 56.0 m
