The figure below shows two blocks with an initial velocity in the same direction. The blocks collide in an elastic collision. The mass of block 1 is 8.0 kg and the before collision velocity of block 1 is 7.3 m/s. The mass of block 2 is 3.4 kg and the before collision velocity of block 2 is 5.6 m/s. The after collision velocity of block 1 is 6.2859649122807 m/s. Determine the after collision velocity of block 2.
