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:
China has about five thousand years history which is a very long period of time. Also, the Chinese civilization was growing with these periods of time and it will continues greater than ever. Many wars and unhappinesses were happening during this period. Although, the time has passed, the histories and the civilizations have not passed. These family virtues, serious, working attitudes, sense of justice and the great Confucian tradition have been deeply assimilated into the Chinese people. Some Chinese traditions are different from North American’s. The Chinese culture has many special characteristics which are very interesting for people to learn. The family life is very important for every Chinese. Chinese families are very…
They will live with the old people because they could like to look after them. This is quite important for Chinese family. Chinese believe that life goes b turn. The old people take care and raise the, when they are young. They should look after them when they are old. The Traditional Chinese houses have many differences in comparison with the North American houses. The building materials used in construction is the most distinct difference from North American’s. A typical Chinese farmhouse is built of sun-dried bricks or pounded earth, because wood is too expensive and scarce to use. On the other hand, many typical Northern American houses are built of wood.
