The stopping Distance of the Car with the given parameters is; 17.43 m
What is the stopping sight distance?
We are given;
mass; m = 1 000 kg
speed; u = 16.7 m/s
Frictional force; F = 8000 N
distance, s = ?
final velocity = 0 m/s (car stops)
Formula for final velocity is;
v² = u² + 2as
but a = negative (deceleration)
And F = ma
Thus;
a = F/m = 8000/1000
a = 8 m/s²
Thus;
0 = (16.7)² - 2(8)(s)
278.89 = 16s
s = 17.43 m
Stopping distance = 17.43 m

Answer:
A very important feature partly in the Sub-Sahara of Africa is the Great Rift Valley which stretches for about 6000km from Syria to Mozambique is a block faulted valley, 30 to 60 miles wide which represents a rift in the African plate of plate tectonics, similar to the ones under the ocean like the mid-Atlantic ridge. It has fertile soil in it, partly from volcanoes like Mt Kilimanjaro, and also many large lakes like Lake Tanganyika, It provided a rich environment due to the soil and the lakes for example, for the Bantu people in the past, many of which had their kingdoms here. Ancient human remains have been found in its soil by Richard Leakey.
I run a book club with $n$ people, not including myself. every day, for $365$ days, i invite three members in the club to review a book. what is the smallest positive integer $n$ so that i can avoid ever having the exact same group of three members over all $365$ days?
The smallest positive integer n so that you can avoid ever having the exact same group of three members over all 365 days is; 11
How to solve probability combination?
if we have n people and we want to do groups of 5, the total number of different combinations is:
ⁿC₅ = n!/((n - 5)!5!)
By using the Brute force method, we have;
If n = 5,
c = 5,
Thus;
C₅ = 5
If n = 6,
c = 6,
Thus;
C₅ = 6
If n = 7,
c = 7,
Thus
C₅ = 21
If n = 8,
c = 8,
Then;
C₅ = 56
Now, If n = 9,
C = 9!/((9 - 5)!5!)
C = 126
We want to find the smallest n such that c > 365. Thus, C = 126 is too small.
Let's try n = 11;
C = 11!/(6! * 5!) = 462
This is greater than 365 and so we need at least 11 members in the club.

What is the Wallerstein’s world systems theory?This theory is an approach towards the world history and social change that suggests there is a world economic system in which some countries benefit while others are exploited.
This theory was developed by a sociologist named Immanuel Wallerstein. It is structured into three tier namely:
core, core, periphery, and semi-periphery.The limitations of the Wallerstein’s world systems theory:

Alice says she can find the area of the room by dividing
I found the complete problem.
If Alice divides it into two trapezoids, the area formula would be: A = [(a+b) / 2] * h
Trapezoid 1
A = [(7.5 + 15)/2 * 5
A = (22.5/2) * 5
A = 11.25 * 5
A = 56.25 sq. ft
Trapezoid 2
A = [(5 + 10)/2 * 7.5
A = (15/2) * 7.5
A = 7.5 * 7.5
A = 56.25 sq. ft
Total area = 56.25 + 56.25 = 112.50 sq. ft.

15.4 segment relationships in circles homework answers
The length of the segment is an illustration of intersecting chords
The value of x is x = 27/14
How to determine the length of the segment?From the complete question (see attachment), we have:
AD = 12
AE = 3
BE = 14
EC = x
Start by calculating the length of ED
ED = AD - AE
This gives
ED =12 - 3
ED =9
The value of x is then calculated as:
x * BE = AE * ED
Substitute known values
x * 14 = 3 * 9
Evaluate the product
x * 14 = 27
Divide both sides by 14
x = 27/14
Hence, the value of x is x = 27/14
