Answer:

Step-by-step explanation:
For the spring mass system
my"+by'+ky=0
The system is said to be critically damped if 
Here b is coefficient of friction
m is the mass of system
And k is spring constant
We have given m = 2 kg , k =1
So 


So the coefficient of friction is
Answer:
the answer is for sure x=0
To solve this problem you must apply the proccedure shown below:
1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)
2. Then, when you solve it, you obtain:
1600+6t^3/2=1984
3. Therefore, as you can see, the answer is: 1984 acres.
Answer:
The value of x if the equation is
3x + 4y=65
x = 49/3 or 16.3
&
3x - 4y=65
x= 27
