Answer:
a=-22.266cm/s^2
Explanation:
A body that moves with constant acceleration means that it moves in "a uniformly accelerated movement", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.
Vf=Vo+a.t (1)\\\\
{Vf^{2}-Vo^2}/{2.a} =ΔX(2)\\\\
X=Xo+ VoT+0.5at^{2} (3)\\
Where
Vf = final speed
Vo = Initial speed
T = time
A = acceleration
X = displacement
In conclusion to solve any problem related to a body that moves with constant acceleration we use the 3 above equations and use algebra to solve
FOR THIS PROBLEM
X=-2.32cm
Xo=4.3cm
Vo=15.3cm/s
t=1.72s
WE USE THE ECUATION 3
a=(X-Xo-Vot)2/t^2
a=(-2.32-4.3-15.3x1.72)2/1.72^2
a=-22.266cm/s^2
Answer:
Douglass thinks that school is not fair. The children came to learn, but they ended up failing and by the schools unfair system. The children do not deserve this, they are all smart in their own ways and not by the schools way.
Explanation:
Answer:
B. That you had
Explanation:
This is dependent on more, it makes no sense by itself so you need more information for it to make sense.
Edgar Allan Poe uses chronological events in "The Black Cat" in order to show the curve of transformation the narrator suffers through the story. At the beginning he used to like the cat very much, but after certain events that happen to him and that lead him to commit certain actions, he starts hating the cat.
Without the chronological events, the story would be very difficult to understand and we wouldn't be able to understand his internal motives to do something like that to the animal he used to love.
The answer is watchfulness
