13:32 why you writed (1-B^2)^2 instead of (1-B^2) in denominator? isn't it wrong?

Look at the equation above for v_i prime. The problem is the first 1+beta^2 in the denominator should be (1+beta^2)^2.

As your initial Imagination At 5:58 When When We are Talking in S'frame after collision observer in S'would observe B is at rest and A is moving in +y direction Thus In S'frame Vx should be Zero and Vy Should Be Non zero
