Answer:
14.8m
Explanation:
Given parameters:
Initial speed = 17m/s
Unknown:
Maximum height = ?
Solution:
At the maximum height, the final speed will be 0m/s;
We use of the kinematics equation to solve this problem.
V² = U² - 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
0² = 17² - (2 x 9.8 x h )
0 = 289 - (9.6h)
-289 = -19.6h
h = 14.8m
Answer:
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within.

Answer:
![v(0)=2m/s](https://tex.z-dn.net/?f=v%280%29%3D2m%2Fs)
Explanation:
The instantaneous velocity of a point mass that executes a simple harmonic movement is given by:
![v(t)=\omega *A*cos(\omega t + \phi)](https://tex.z-dn.net/?f=v%28t%29%3D%5Comega%20%20%2AA%2Acos%28%5Comega%20t%20%2B%20%5Cphi%29)
Where:
![\omega=Angular\hspace{3}frequency\\A=Amplitude\\\phi=Initial\hspace{3}phase](https://tex.z-dn.net/?f=%5Comega%3DAngular%5Chspace%7B3%7Dfrequency%5C%5CA%3DAmplitude%5C%5C%5Cphi%3DInitial%5Chspace%7B3%7Dphase)
Express the amplitude in meters:
![10cm*\frac{1m}{100cm} =0.1m](https://tex.z-dn.net/?f=10cm%2A%5Cfrac%7B1m%7D%7B100cm%7D%20%3D0.1m)
The angular frequency can be found using the next equation:
![\omega=\sqrt{\frac{k}{m} }](https://tex.z-dn.net/?f=%5Comega%3D%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm%7D%20%7D)
Using the data provided:
![\omega=\sqrt{\frac{400}{1} } =20](https://tex.z-dn.net/?f=%5Comega%3D%5Csqrt%7B%5Cfrac%7B400%7D%7B1%7D%20%7D%20%3D20)
At the equilibrium position:
![\phi=0](https://tex.z-dn.net/?f=%5Cphi%3D0)
![v(0)=20*(0.1)cos(20*0+0)=2*cos(0)=2*1=2m/s](https://tex.z-dn.net/?f=v%280%29%3D20%2A%280.1%29cos%2820%2A0%2B0%29%3D2%2Acos%280%29%3D2%2A1%3D2m%2Fs)
The aqueous solution will most likely be a base.
