Question

U=1/2kx^2 What is x equal to?

Answer 1

Answer:

           $\bold{x=\sqrt{\dfrac{2U}{k}}}$

Step-by-step explanation:

                                         $U=\frac12kx^2\\\\2U=kx^2\\\\\dfrac{2U}k=x^2\\\\x=\sqrt{\dfrac{2U}k}$

or if you miswrite and it should be: U=1/(2kx^2), than

$U=\dfrac1{2kx^2}\\\\\dfrac1U=2kx^2\\\\\dfrac1{2kU}=x^2\\\\x=\sqrt{\dfrac1{2kU}}$
