For a...

[tex]v=\frac{m_1v_1+m_2v_2}{m_1+m_2}[/tex]

for b...

[tex]x_m=\sqrt{\frac{m_1(v_1-v_2)^2}{k}}[/tex]

for c...

[tex].5kx_m^2=.5m_1v^2[/tex]

[tex]v=\sqrt{\frac{kx_m^2}{m_1}}[/tex]

however the problem doesnt say in terms of [tex]x_m[/tex]

I'm not sure what to do. If I plugged in b, it would give me v=v

not quite sure

is that right?
