0Two balls of masses \( m_{1} \) and \( m_{2} \) are moving towards each other with speeds \( u_{1} \) and \( u_{2} \), respectively. They collide head-on and their speeds are \( v_{1} \) and \( v_{2} \) after collision
\( \mathrm{P} \) \( \left(m_{1}=8 \mathrm{~kg}, m_{2}=2 \mathrm{~kg}, u_{2}=3 \mathrm{~m} / \mathrm{s}\right) \).
