j'ai vu que plusieurs fois vous avez corrigé "j'espère qu'il va..." et avez utilisez "aille(subjonctif)" Ceci est faux.La forme correcte est bien "j'espère qu'il va..." Cordialement, (quel est votre niveau en français?)

The answer you want is Va (Andy's velocity), 10 m/s. I was just trying to show you more of the steps of solving the problem. I never said the answer was 4 m/s. That is the DIFFRERENCE between the speeds. You did not read my answer very carefully. If you had, you would have ...

math
use conservation of momentum. Ma*Va+Mb*Vb=Ma*Va' + Mb*Vb' 28(Ma-Mb)= well, at this point, you have two unknowns, and you have to stop. You cannot use conservation of energy, you have no basis to assume it was an elastic collision.
