$\frac{1}{2}{m_1}{u_1}^2 + \frac{1}{2}{m_2}{u_2}^2 = \frac{1}{2}{m_1}{v_1}^2 + \frac{1}{2}{m_2}{v_2}^2 - \varepsilon $
- B
$\;\frac{1}{2}{m_1}{u_1}^2 + \frac{1}{2}{m_2}{u_2}^2 - \varepsilon = \frac{1}{2}{m_1}{v_1}^2 + \frac{1}{2}{m_2}{v_2}^2$
- C
$\;\frac{1}{2}{m_1}{u_1}^2 + \frac{1}{2}{m_2}{u_2}^2 + \varepsilon = \frac{1}{2}{m_1}{v_1}^2 + \frac{1}{2}{m_2}{v_2}^2$
- D
$m_1^2u_1+m_2^2u_2 - \varepsilon = m_1^2v_1+m_2^2v_2$
