Abody moving with uniform acceleration has a velocity of 15.3 cm/s when its x coordinate is 4.3 cm. if its x coordinate 1.72 s later is −2.32 cm, what is the x-component of its acceleration? answer in units of cm/s 2 .

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

it’s important not to respond to the bully because doing so generally just escalates the problem.

tell a trusted adult about what is happening and save the evidence. you should also let your internet or cell phone provider know, along with the operator of the site if it is happening online.

if the bullying continues, notify the local police and consider consulting an attorney if it becomes serious.

school authorities may also become involved if it involves students on campus.
