A satellite traveling 800 m/s approaches a second satellite that is at rest. They both have the same mass. What will happen to their speeds when they connect and move off together?
[tex]\bullet~\text{Mass of each satellite:}~m\\\\
\bullet~\text{Linear momentum of the first satellite:}\\p_1=m_1v_1=m\cdot800\Longrightarrow p_1=800m\\\\
\bullet~\text{Linear momentum of the second satellite:}~\\p_2=m_2v_2=m\cdot0\Longrightarrow p_2=0~kg\cdot m/s\\\\
\bullet~\text{Linear momentum of the connected satellites:}~\\p'=m'v'=(m_1+m_2)\cdot v'=(m+m)\cdot v'\Longrightarrow p'=2mv'\\\\
