Question

The formula E =1/2 kx^2gives the potential energy E of a spring with spring constant k that has

Answer 1

Answer:

$\sf\longmapsto \: k = \frac{2E}{x {}^{2} }$

Step-by-step explanation:

The formula given is :

$\sf\longmapsto \: E = \frac{1}{2} kx²$

Now, multiply (×) both sides by 2 and divide (÷) by x^2

$\sf\longmapsto \: 2E = kx²$

$\sf\longmapsto \: k = \frac{2E}{x {}^{2} }$

Answer 2

Answer:

• $k = 2E/x^2$

Step-by-step explanation:

Given formula:

• $E = 1/2kx^2$

To solve for k, multiply both sides by 2 and divide by x²:

• $2E=kx^2$
• $k = 2E/x^2$
