Answers:
a) 1.224 s
b) -27.2 m/s
c) -37 m/s
Step-by-step explanation:
According to the given information the distance is given by:
(1)
In additio, since the projectile was fired vertically we can use the following equation:
(2)
Where:
is the final velocity
is the initial velocity
is the acceleration due gravity
is the time
Knowing this, let's begin:
a) Find for
Using (2):
(3)
(4)
(5)
(6)
b) Find for
In this case we have to find :
(7)
(8)
c) Find for
(9)
(10)
<u>Conclusions:</u>
The time we found in a) when is at the maximum height of the projectile, just before going down. That is why in parts b) and c) when time is and the velocity is negative, because it is directed downwards.
The p-value falls between 0.025 and 0.05 is my guess, since we have t = -1.45 in 25 observations. The test of H0 against Ha show that μ = 7.2 and μ < 7.2 means μ = μ (7.2 = 7.2).
Answer:
sentence 2?
Step-by-step explanation:
sentence 1 provides background for the question, sentence 2 provides background for the graph, and sentence 3 is the question.
If you wanted the answer to the question:
8:4 = 2:1
Just find two ordered pairs that are whole numbers and use the slope formula:
Two ordered pairs that are wholes numbers that I found are (0, 4) and (1, 1)
Plug in the values.
So, the answer is C -3.
