Answer:
(0, 9)
Step-by-step explanation:
The midpoint coordinates are the averages of the end point coordinates.
M = (A +B)/2
M = ((8, 10) +(-8, 8))/2 = (8 -8, 10+8)/2 = (0, 18)/2
M = (0, 9)
The midpoint is (0, 9).
Full Question
A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time t = 0, the resulting mass—spring system is disturbed from its rest state by the force F (t) = 20 cos(8t). The force F (t) is expressed in Newtons and is positive in the downward direction, and time is measured in seconds.
Determine the spring constant k.
Answer:
Spring Constant = 1000Nm^-1
Step-by-step explanation:
Given
Mass = 10kg
Spring Extension = 9.8cm
Spring Constant K = Force/Extension
Force = Mass * Acceleration
Force = 10 * 9.8 = 9.8N
Spring Extension = 9.8 cm = 9.8 /100 = 0.098 m
Spring constant = 98 / 0.098
Spring Constant = 1000Nm^-1
Answer: 2.2% I’m not sure (ps. I’m really not sure like this is what I think it is butttt someone’s answer might be better so go with there’s)
The correct answer is option A which is the distance between A and D will be AD = 
.
<h3>What is coordinate geometry?</h3>
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
The formula utilised to find the distance between two points is;-
X = 
We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.
AD = .
Therefore the correct answer is option A which is the distance between A and D will be AD = .

Its 110 cuz it goes up 10% if it was 20% it would be 120
