Answer:
I think its b if you get it right tell me or no
Technician B only is right, who says that to avoid warping the cylinder head, the engine must be cold before removing it.
<h3>What is the cylinder head doing in my car?</h3>
The main task of the cylinder head is to close the discharge chamber of the engine from the top. The upper part of the engine is reached the cylinder head, while the lower part is the engine partnership.
The cylinder head sits on the engine and shuts off the combustion chamber. The gap that remains between the cylinder head and the engine is achieved by the head gasket.
<h3>How to recognize signs of possible defects</h3>
If you notice abnormalities in the functioning of your engine, it is advisable to contact a garage as soon as feasible to prevent further injury.
- The signs of cylinder head flaws include:
- You notice a power loss of the machine
- The cooling water temperature is in the red area
- You see oil in the cooling water
- You must supply water and oil after just a short time
- You notice a bad cold start behavior

Answer:
![v(t)=-\frac{5}{2}\sqrt{t^3}+20\\s(t)=-\sqrt{t^5}+20t](https://tex.z-dn.net/?f=v%28t%29%3D-%5Cfrac%7B5%7D%7B2%7D%5Csqrt%7Bt%5E3%7D%2B20%5C%5Cs%28t%29%3D-%5Csqrt%7Bt%5E5%7D%2B20t)
![s(t=4)=48\text{ m}](https://tex.z-dn.net/?f=s%28t%3D4%29%3D48%5Ctext%7B%20m%7D)
Explanation:
In this case acceleration is defined as:
,
where k is a constant to be found.
To find the expressions for velocity and position as a function of time you must integrate the expression above for acceleration two times.
Initial conditions and boundary conditions are defined with the rest of the data as:
![v(t=0)=20\text{ m/s}\\v(t=4)=0\text{ m/s}\\s(t=0)=0\text{ m}](https://tex.z-dn.net/?f=v%28t%3D0%29%3D20%5Ctext%7B%20m%2Fs%7D%5C%5Cv%28t%3D4%29%3D0%5Ctext%7B%20m%2Fs%7D%5C%5Cs%28t%3D0%29%3D0%5Ctext%7B%20m%7D)
First integration is equal to:
![a'(t)=v(t)=-k\int\sqrt{t}dt=-\frac{2}{3}k\sqrt{t^3}+C_1](https://tex.z-dn.net/?f=a%27%28t%29%3Dv%28t%29%3D-k%5Cint%5Csqrt%7Bt%7Ddt%3D-%5Cfrac%7B2%7D%7B3%7Dk%5Csqrt%7Bt%5E3%7D%2BC_1)
The boundary condition and initial condition can be used to calculate
and
:
![C_1=20\\k=\frac{15}{4}](https://tex.z-dn.net/?f=C_1%3D20%5C%5Ck%3D%5Cfrac%7B15%7D%7B4%7D)
With this expression for velocity is defined as:
![v(t)=-\frac{5}{2}\sqrt{t^3}+20](https://tex.z-dn.net/?f=v%28t%29%3D-%5Cfrac%7B5%7D%7B2%7D%5Csqrt%7Bt%5E3%7D%2B20)
The same can be done to get to expression for position:
![s(t)=-\sqrt{t^5}+20](https://tex.z-dn.net/?f=s%28t%29%3D-%5Csqrt%7Bt%5E5%7D%2B20)
To get the total distance traveled you can integrate the velocity expression from time=0 sec to time=4 sec:
![s_{tot}=\int_0^4(-\frac{5}{2}\sqrt{t^3}+20)dt=48\text{ m}](https://tex.z-dn.net/?f=s_%7Btot%7D%3D%5Cint_0%5E4%28-%5Cfrac%7B5%7D%7B2%7D%5Csqrt%7Bt%5E3%7D%2B20%29dt%3D48%5Ctext%7B%20m%7D)
