Question

The potential energy , p in a spring is represented using the formula p=1/2kx2. Lupe uses an equivalent equation, which is solved for k , to determine the answers to her homework . Which equation should she use

Answer 1

p=1/2kx²

To get the equivalent formula, we make k the subject

p=1/2kx²

Multiply both sides by 2

2p = kx²

Divide both sides by x²

2p/x² = k

∴ the equivalent formula is;

k = 2p/x² 

Answer 2

Answer:

Step-by-step explanation:

as given equation $p=\frac{1}{2k}x^{2}$

we have to find the value of k

so$p=\frac{1}{2k}x^{2}\\\\p*2k=x^{2}\\\\k=\frac{x^{2}}{2p}$
