A brick of mass 4 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 3 cm. The spring is t

Zielflug [23.3K]

Answer:

Step-by-step explanation:

In this system we have the force of the spring and the gravitational force. The equation that describes that is

$F_{s}+F{g}=ma\\k(y_0+y)-mg=ma$

where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have

$ky_0+ky-mg=ma\\mg+ky-mg=ky=ma\\\\ky=m\frac{d^2y}{dt^2}\\\\my''+ky=0$

the solution for this differential equation is (by using the characterisic polynomial)

$y(x)=Acos(kt)+Bsin(kt)\\k=\omega^2m$

hope this helps!!

What is the inverse function of f(x)= 4- x/6

Westkost [7]

Answer:

$f^{-1}(x) = 6(4-x) = 24-6x$

Step-by-step explanation:

Let $y=f(x)$ and swap x and y:

$x = 4 - \frac{y}{6}$

Then, rearranging for y:

$x+\frac{y}{6} = 4$

$\frac{y}{6}= 4-x$

$y= 6(4-x) = 24-6x$
