Question

The potential energy, P, in a spring is represented using the formula P = P equals StartFraction one-half EndFraction k x squared.kx2. Lupe uses an equivalent equation, which is solved for k, to determine the answers to her homework.

Answer 1

Answer:

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

Step-by-step explanation:

The question is

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

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