A block of mass 1.77 kg sliding with a constant velocity of 4.89 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.30 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision. What will be the speeds of the 1.77-kg and 4.30-kg blocks, respectively, after their SECOND collision with one another?
