Kinetic\  energy=\frac{1}{2}mass*velocity^2\\\\
Kinetic energy=\frac{1}{2}*1500*29^2\\\\ Kinetic \ energy=750*841=630750J\\\\
Kinetic \ energy\  is\  equal\  to\  630750\ Jules.

The suspension system of a 1700 kg automobile "sags" 7.7 cm when the chassis is placed on it. Also, the oscillation amplitude de
spin [16.1K]

Answer:

the spring constant k = 5.409*10^4 \ N/m

the value for the damping constant \\ \\b = 1.518 *10^3 \ kg/s

Explanation:

From Hooke's Law

F = kx\\\\k =\frac{F}{x}\\\\where \ F = mg\\\\k = \frac{mg}{x}\\\\given \ that:\\\\mass \ of \ each \ wheel = 425 \ kg\\\\x = 7.7cm = 0.077 m\\\\g = 9.8 \ m/s^2\\\\Then;\\\\k = \frac{425 \ kg * 9.8 \ m/s^2}{0.077 \ m}\\\\k = 5.409*10^4 \ N/m

Thus; the spring constant k = 5.409*10^4 \ N/m

The amplitude is decreasing 37% during one period of the motion

e^{\frac{-bT}{2m}}= \frac{37}{100}\\\\e^{\frac{-bT}{2m}}= 0.37\\\\\frac{-bT}{2m} = In(0.37)\\\\\frac{-bT}{2m} = -0.9943\\\\b = \frac{2m(0.9943)}{T}\\\\b = \frac{2m(0.9943)}{\frac{2 \pi}{\omega}}\\\\b = \frac{m(0.9943) \ ( \omega) )}{ \pi}

b = \frac{m(0.9943)(\sqrt{\frac{k}{m})}}{\pi}\\\\b = \frac{425*(0.9943)(\sqrt{\frac{5.409*10^4}{425}) }    }{3.14}\\\\b = 1518.24 \ kg/s\\\\b = 1.518 *10^3 \ kg/s

Therefore; the value for the damping constant \\ \\b = 1.518 *10^3 \ kg/s

What is the surface area to volume ratio of this cube
tamaranim1 [39]

I can't see that cube from here.

But if the length of the side of the cube is ' K ' units,
then the surface area of the cube is  6K² units², and
the volume of the cube is  K³ units³.

The ratio of the surface area to the volume is

               (6K² units²) / (K³ units³)  =  (6) / (K units) .

So for example, if the side of the cube is 2 inches, then
the ratio of surface area to volume is  "3 per inch".

That's the answer.  I did the whole thing in order to earn
the points, but I don't expect you to understand much of it,
because I see from your username that you suck at math.
I'm sorry you decided that.  Now that you've put up the
brick wall, it'll be even harder for any math to find its way
in there, and you'll miss out on a lot of the fun.

Which type of sedimentary rock is formed from rock and mineral fragments weathered from rocks at earth’s surface?
Zanzabum

Answer:

The correct answer is detritic rocks.

Explanation:

Sedimentary rocks are rocks formed by the accumulation of sediments, particles of various sizes that are transported by water, ice or wind, which are subjected to physical and chemical processes, resulting in consolidated materials.

Sedimentary rocks formed from the accumulation of mineral deposits and rocks from erosion and deposited by gravity are called detritic rocks.

Have a nice day!
