A particle of rest mass mo and speed v collides with a stationary particle of mass M and sticks to it. What is the final speed of the composite particle?
1
\(v_0 = \frac{\gamma m_0 c}{ m_0 + \gamma M}\)
2
\(v_0 = \frac{\gamma m_0 c}{\gamma m_0 - M}\)
3
\(v_0 = \frac{\gamma m_0 v}{\gamma m_0 + M}\)
4
\(v_0 = \frac{\gamma m_0 v}{ m_0 + \gamma M}\)
