# HW 10 Question 6

So I am having problems solving for the height of Block M2 after the collision.  I have gotten the height of block one through the conservation of energy and momentum methods, and tried to re-substitute values and it was incorrect. Help?
$$v_{1f}=\frac {m_1-m_2}{m_1+m_2}v_{1i}+\frac {2m_2}{m_1+m_2}v_{2i} \\ v_{2f}=\frac {2m_1}{m_1+m_2}v_{1i}+\frac {m_2-m_1}{m_1+m_2}v_{2i}$$
