anonymous one year ago Okay, I know I am over thinking this, how do I get two equations since I have 2 unknowns in this problem?

1/ calculate the spring energy at $$t_o$$ 2/ recognise that momentum requires that the bodies must at all times observe $$m_av_v + m_bv_b = 0$$

but wouldn't it be $1/2*k(x)^{2}=m _{A}v_{1}+m_{B}v_{2}$

$\Delta W= -\Delta U_{s}$ $-(\frac{ 1 }{ 2}kx _{f}^2-\frac{ 1 }{ 2 }kx _{i}^2)=(\frac{ 1 }{ 2 }mv _{f}^2-\frac{ 1 }{ 2 }mv _{i}^2)$
