The potential energy, P, in a spring is represented using the formula P = 1/2kx2. Lupe uses an equivalent equation, which is sol ved for k, to determine the answers to her homework. Which equation should she use? k = 2Px2
k = 1/2Px2
k = 2p/x^2
k = p/2x^2

Answer:
Step-by-step explanation:
The formula is
<em>We need to solve for , so we can perform the steps shown below:</em>
Hence, the third answer choice is correct.
We need to find a way to get k by itself so lets get it by itself. For convenience I will switch the equal sign. 1/2kx^2 = p Multiply both sides by 2 kx^2 = 2p divide by x^2 k = 2p/x^2
