how to transpose the formula T=2pi *sqrt(m/k) so k is the subject
You see that your [tex]k[/tex] is inside the square root. Maybe squaring both sides of the equation might help?
would that make it T^2 = (2pi)^2 *(m/k) ???
Good work. You're only one step away. Remember that you want to find an equation [tex]k = ??[/tex].
What if we multiply both sides by [tex]k[/tex], and then divide both sides by [tex]T^2[/tex]?
