A mass weighing 9 lb stretches a spring 1.5 in. The mass is displaced 5 inch in the downward direction from its equilibrium position and released with no initial velocity. Assuming that there is no damping, and that the mass is acted on by an external force of 5 cos(6t) lb, solve the initial value problem describing the motion of the mass. For this problem, please remember to use English units: ft, lb, sec.
Answer:
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
Step-by-step explanation:
Given
[tex]w =9lb[/tex] --- weight
[tex]L = 1.5in[/tex] --- stretch
[tex]u(0) =5in[/tex] --- initial position
[tex]u'(0) =0[/tex] --- initial velocity
[tex]\gamma =0\ lbs/ft[/tex] --- no damping
[tex]F(t) = 5cos(6t)\ lb[/tex] -- External force
Required
Solve the initial value problem
The initial value problem is calculated using:
[tex]mu" + ku = F(t)[/tex]
First, convert all lengths to ft
[tex]L = 1.5in[/tex]
[tex]L = \frac{1.5}{12}ft[/tex]
[tex]L = \frac{1}{8}ft[/tex]
[tex]u(0) =5in[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex]
Weight is calculated as:
[tex]w = mg[/tex] and [tex]w = kL[/tex]
Where
[tex]g = 32fts^{-1}[/tex]
Make m the subject in [tex]w = mg[/tex]
[tex]m = \frac{w}{g}[/tex]
[tex]m = \frac{9}{32}[/tex]
Make k the subject in [tex]w = kL[/tex]
[tex]k = \frac{w}{L}[/tex]
[tex]k = \frac{9}{1/8}[/tex]
[tex]k = 72[/tex]
Recall that: [tex]mu" + ku = F(t)[/tex]
[tex]\frac{9}{32}u" + 72u = 5cos(6t)[/tex]
Multiply through by 32
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]

If f(x)=x^3-x, what is the average of change of f(x) over the interval [1,5]
Given:
The function is:
[tex]f(x)=x^3-x[/tex]
To find:
The average of change of f(x) over the interval [1,5].
Solution:
We have,
[tex]f(x)=x^3-x[/tex]
At x=1, we have
[tex]f(1)=(1)^3-(1)[/tex]
[tex]f(1)=1-1[/tex]
[tex]f(1)=0[/tex]
At x=5, we have
[tex]f(5)=(5)^3-(5)[/tex]
[tex]f(5)=125-5[/tex]
[tex]f(5)=120[/tex]
The average of change of f(x) over the interval [a,b] is
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Now, the average of change of f(x) over the interval [1,5] is
[tex]m=\dfrac{f(5)-f(1)}{5-1}[/tex]
[tex]m=\dfrac{120-0}{4}[/tex]
[tex]m=\dfrac{120}{4}[/tex]
[tex]m=30[/tex]
Therefore, the average of change of f(x) over the interval [1,5] is 30.
Solve: 6(8+7a)≤132 I really need hellpppp
Answer:
a ≤ 2
Step-by-step explanation:
Simplify both sides of the inequality
42a + 48 ≤ 132
Subtract 48 from both sides
42a + 48 − 48 ≤ 132 − 48
42a ≤ 84
Divide both sides by 42
42a/42 ≤ 84/42
a ≤ 2
A flight with 104 passengers takes off at 1:15. The plane travels 560 miles in 1 hour. At that speed, how far will the plane travel in 3 hours? What information is needed to answer the question?
Answer:
To find how far the plane will travel, we need the time and length it traveled previously to form the MPH (miles per hour)
Using this information we can make an equation
560/1 = 560 miles in 1 Hour
x/3 = X miles in 3 Hours
560/1 = X/3
X= 1680

Rewrite with only sin x and cos x.
sin 3x - cos x (6 points)
Select one:
a. 2 sin x - sin3x - cos x
b. 2 sin x cos2x + sin x - 2 sin3x - cos x
c. 2 sin3x cos4x + 1
d. 3 sin x cos x - sin3x - cos x
Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx

how many odd positive integers greater than 50 and less than 140 are there?
Step-by-step explanation:
there are 45 odd numbers
Answer:
45
Step-by-step explanation:
to figure this out, lets first subtract 50 from 140 so we can start at 0, it will be easier to calculate and we will get the same result
140 - 50 = 90
then since theres 1 odd intager for every even intager in an even set of numbers, we can divide 90 by 2 to get the amount of odd intagers
90 / 2 = 45
if you start at 0, 50, or even 5 million, as long as the difference between the two thresholds stay the same, you will get the same result
