    A H atom, travelling at 5000 m s-1collides with a H2 molecule at rest and reacts asfollows
    H + H2 → H2 + H

    Assuming that the H2 molecules before and after the collision have zero vibrationaland rotational energy find the final velocity of H and H2 .

    How would I go about this? I think it has to do with conservation of momentum but idk how to apply it

    You should have the mass of hydrogen somewhere then using mv=mv before=after
