The potential energy, P, in a spring is represented using the formula P = P equals StartFraction one-half EndFraction k x square

Anastaziya [24]

Answer:

$k=\frac{2P}{x^{2}}$

Step-by-step explanation:

<u><em>The question is</em></u>

Which equation should she use?

we have the formula

$P=\frac{1}{2}kx^{2}$

Solve for k

That means ----> isolate the variable k

Multiply by 2 both sides

$2P=kx^{2}$

Divide by x^2 both sides

$\frac{2P}{x^{2}}=k$

Rewrite

$k=\frac{2P}{x^{2}}$

Find the equation of the line with slope = -5 and passing through (4,-17). write your equation in the form y = m x + b y=mx+b.

RUDIKE [14]

Y=mx+c
m= -5

Just substitute the values of the point into the equation to find c

-17=-5 x 4 +b
-70+20+b
3=b

y=-5x+3

Hope I helped :)
