0.40\,\text{kg}

cart A moves at

2.0\,\text{m/s}

toward a

0.60\,\text{kg}

cart B that is at rest on a frictionless track. They stick together on impact. The joined pair then collides elastically with a

1.0\,\text{kg}

cart C that was initially at rest on the track. Determine the speed of cart C after the second collision is complete.
