- E=1/2kA^2=1/2m(wA)^2

So first I find the energy using the eqn (1/2)kA^2. Since there are two springs with the same k I multiply it by two to get kA^2. Energy I get is 2.0475,

Now I use E=(1/2)m(wA)^2 to find mass. Again since there are two springs I use E=m(wA)^2.

m=E/(wA)^2. w=(2(pi))/T btw.

I get the answer of 3.375 when the correct answer is 6.750. Why is it that multiplying my answer by 2 gives me the rights answer? what am i missing here
