i had the exact same problem on my acellus
To answer this question, you need to determine the altitude difference and speed difference of plane B and plane A.
The initial altitude difference should be: 5000 feet- 3586 feet= 1414 feet.
The speed difference should be: 30.25 ft/s - 55.5 ft/s= - 25.25ft/s
After that, you can determine how long will pass before the plane in the same altitude.The calculation would be:
Final altitude difference= Initial altitude difference + speed difference*time
0 ft= 1414 ft + (-25.25ft/s * time)
25.25 time= 1414s
time= 56 second
To determine the altitude you just need to sample either plane A or plane B. Let's use plane B for easier initial altitude. The calculation would be:
Final altitude= initial altitude + speed*time = 5000ft + 30.25ft/s *56s= 6694ft
Answer:
The equation of the parabola is (x-2)^2 = 48(y-5)
Step-by-step explanation:
Mathematically, we can obtain the equation of a parabola from its focal point and the directrix given.
Firstly, we need to find the distance between the director and the vertex
That would be ;
|-7-(5)| = 12
We should kindly note that the directrix is below the vertex and thus it is a right-side parabola with a positive value of p = 12
Thus, the equation needed would be;
(x-h)^2 = 4p(y-k)
From the question, h = 2
p = 12 ( calculated) and k = 5
So the equation would be;
(x-2)^2 = 4(12)(y-5)
= (x-2)^2 = 48(y-5)
Ummm look it up or ask the teacher I thought I had the answer but I don’t sorry
